OpenBox Athletics | Functional Fitness Training, CrossFit, Boot Camp, Small Group Fitness Gym

My drop- in experience was great. I appreciate how attentive Trey and Russ were. Everyone in the class was very welcoming as well. I'm definitely interested in trying out the Colider class next. Thanks so much for the warm welcome. My body is so sore, which means we were putting in work! Love it!

Thank you Coach Russ for the encouragement and support!

Great coach! Melanie is knowledgeable and motivating in every session. CrossFit can be really challenging, but with her guidance at OpenBox Athletics | Functional Fitness Training, CrossFit, Boot Camp, Small Group Fitness Gym, the workouts become fun and engaging. She pays close attention to my form, adjusts the weights when needed, and always encourages me to push a little further without overdoing it. I can clearly feel my progress week by week - movements that once felt tough are now smoother and more controlled. The energy she creates in the gym makes even the hardest workouts enjoyable, and that keeps me coming back.

Love Emily! Always gives good energy. Precise with instruction but also understanding of different stages of growth at the same time.

I want to thank all the amazing coaches that help me and everybody else in the class stay fit and healthy.

thanks to the coaches who support masters athletes and give us the space and patience we need.

Joining OBA has been the best decision I have made for me and my health! I feel stronger than ever and couldn’t do it without the amazing community at OBA. Thanks to everyone at OBA, specially to the coaches for helping me through this journey!

Trey was really great! His instructions were very clear and he kept class’s attention with his high energy and humor. He offered options and allowed adjustments to folks in sensible ways. I had a really good time.

Great coach! Always makes class fun

Liv always makes sure to motivate us, keep us on track, and keep our form in check. Love hearing her tips and tricks and the way she demonstrates movements!

Melody is the gold standard for coaching. She’s organized, professional, personable, and easygoing. I’m not sure how it’s possible for one person to be so perfect.

Always good energy :)

Russ is a great coach with so much positive energy and a personality that makes you wanna work! Also does a fab job explaining the workouts and modifications. Thank you!!

He was great at scaling and showing me proper form. As a beginner, I really appreciate the “no judgement” approach to scaling and learning!

Always look forward to classes with Matt! His instruction is always constructive & his energy is consistently positive and engaging.

How did the coach help you today?

Always provides great feedback, keeps classes on track, personable and helpful!

Lis was awesome! Great motivator and helped provide in the moment feedback to help with my form.

Love classes with coach Liv! Question: do these go somewhere? Like as part of some sort of evaluative process or is it vibes? I’d take them more seriously if so lol

Melody is always

Today was my first class after a long hiatus. It felt so good to move again! Jean was very accommodating, which helped me get back into moving my body with confidence and care. Looking forward to the next class!

Jean was awesome and helped me to reacclimate to the drills. Thank you, Jean!

Coach was thorough in explaining workout and movements/form. Felt comfortable in first class in gym

Melanie is awesome. She commands the room in a funny yet serious manner. she’s knowledgeable, obsessed with proper form and always makes herself available for questions/modifications. Love her classes!

Great class as always! Helpful breakdown of each exercise.

Mike was awesome!! First class here and was super friendly/helpful. Really made me feel welcome in the space!

Friendly thorough explanations and alternate movements to accommodate!

Emily and Mike were excellent instructors and kept things loose. I appreciated their coaching throughout the session.

Lis always makes me feel welcome at gym. She explains required workout posture very well and hell me understand quicker with easily understandable terms

Wonderful!

Matt is super.

Jean is exceptional. She provides fantastic coaching, encouragement, and knowledge. She also has impeccable taste in workout music during class

Really organized and great at explaining each Colidr station. First Colidr class was awesome

Great coach and great sense of humor with an excellent taste in music.

Good job! This is also for coach melody she’s not on the list. They were both great!

Emily always knows when I mess up and is ready to help!

She’s thoughtful in how she prepares us for the movements and provides feedback as needed throughout the workout. She also does not play the music too loud.

Tip top

Matt led us through a great warm up and mobility exercises to prepare for the 1 rep max front squat lift for the day.

Lis is always awesome! It was a good workout.

Crossley is great!! She makes sure your technique is proper. It’s about quality reps with her not about speed. I appreciate that!

Amazing!!! Great Class!!

Always love attending Jean's classes! Her explanation of the exercises are always clean and I appreciate her tips and encouragement.

Awesome first class with Emily ! Very supportive and personable.

Have been coming for 5 weeks ish now! Love the class and love how balanced the workouts always are with the right amount of challenge. Emilys great!

I like almost everything and the variety. I just wish we would have access to Open gym more hours during the weekend. (Pm). But is not a deal breaker

Trey and Russ led an amazing class and they took time to go over the snatch and clean thoroughly.

Omg amazing class. First time here! I’m visiting family in Philly and need a place to go to work out when I’m here. I think I’ve found the place!!!! Thank you to my two female coaches! Excellent experience. I wasn’t going to get hurt or have bad form on their watch! That’s my goal!

Alexa is the best. She is great at scaling the workout for my abilities and motivates me to work harder.

Always look forward to dropping in when I visit Philly and had an excellent and fun class with Matt, as always!

Both of the coaches were very helpful and gave me individual attention to make me feel at ease.

As always, he brought an energetic morning vibe to the class, with easy to understand instructions

Start to finish, fantastic! Great atmosphere, warm up, and work out.

Lis is a very dedicated coach. Highly recommended

I’m new to CF. Technique and consistency is critical for me especially now so this 56yo body doesn’t get injured and stop attending. Not only is OBA super friendly to rookies, they are also super attentive to my newbie needs. Matt came over several times to review my mistakes - and how to correct them. OBA is the BEST.

Emily is a great coach. She is super thoughtful about her feedback and is encouraging, which is helpful when trying a new movement. I appreciate her can do attitude especially in the morning when we are all waking up still

Today I did a Crossfit drop in from Tampa FL. Trainer Matt was awesome and very active coaching. The box was super clean and the people were very nice. I will be dropping in whenever I am in Philly!

Matt did a great job demoing how to lift the bag without injuring your back.

Emily is great - one of my favorite OBA coaches! She’s super friendly and approachable, offers helpful alternatives and suggestions for a good and challenging workout. I so appreciate her enthusiasm and encouragement when things get hard! She knows I am training for a Half Marathon in November and I think it’s so thoughtful that she always remembers to ask me how my training is going. Thanks Emily! In case my other favorites read this too - shout out to Jean, Crossley, and Lis! 💕

Being new to cross fit and new to some of the exercises in the workout. Everyone in the class was helpful and the coaching was great to explain how to do the workout and how to improve my form. Great first class.

I’ve really enjoyed working with you as a coach! You have a great way of explaining concepts in a simple and motivating way that sticks. Every session I’ve walked away with something practical I could apply right away, and I can honestly say I’ve grown a lot because of your coaching. I also appreciate how encouraging and approachable you are—it makes learning fun and easy to stay consistent. Thank you for all the support!

Fabulous!!

I don’t take a specific class. I go for open gym. I like the energy, focus, and friendly environment. It is very straight forward, genuine and motivating. Staff is very cordial and attentive, and I like being treated as a capable and responsible adult. I’m very happy I signed up, and look forward to continued development in there.

Emily is awesome! Great coaching and great class!

I have never had a coach I didn’t like at OBA! Emily is always so helpful and so willing to give me ideas on how best to complete the workout. I’m an older athlete and I like coming to CrossFit many times a week. I so appreciate Emily’s help and feedback in how to get the most out of my workout, and be safe.

Great attention! Loved her modifications!

Trey is an excellent coach. Always so attentive, and ready to help you. He describes the workout in a way that is very easy to understand and takes time to explain each part of it to make sure everyone is in the same page.

Class was excellent with Trey he spoke very clearly and he really gives you that extra push to keep going.

Trey coached another awesome Colidr class as always! I left class feeling great & he’s always attentive in helping me correct my form and posture, which makes me feel both supported and confident throughout the workout. I honestly can’t say enough great things about OBA and all of the coaches.

Olivia was great! Gave great demos and explained the work out so well!

Lis was super welcoming and took the time during class to give clear, detailed instructions on proper form

Great; I always enjoy class with Lis

Instructor was very patient. He took the time to demonstrate every exercise and check in on members during the workout. Very positive and professional attitude

Very energized and helpful during the work out.

Jean is an excellent coach—knowledgeable, attentive, and encouraging. She’s always supportive, making sure everyone uses proper form and offering gentle adjustments when needed. It’s a pleasure having her coach!

Class was easy to follow and each exercise was demonstrated so we all knew what we had to do. I love that she gives variations and scaling options.

Lis is always great with her coaching. I learn something new almost every class in regards to form. She is always open to conversation and providing feedback after class which is appreciated!

Coach did a great job explaining each work out and answering questions. I left feeling sweaty and tired.

Trey did amazing coaching! You guys need to make him a possible coach selection. I think he has the chops to make it out there in the cruel hard world. He really brought the thunder I needed to get the gains I deserve. I will absolutely be back to see Trey.

Amazing, very engaged and encouraging

Jean is always an amazing coach - she always makes us laugh even at 6:30 on a Monday morning! Beyond that she’s skilled with making any workout easier or harder to match skill level. It’s also good to know she watches your form and technique to make sure you are working the muscles exactly as intended - but be ready for a good sweaty workout!

Matt is always nice and friendly, and he creates a welcoming workout environment for everyone. He explains every detail clearly so that all members can easily understand. Plus, he suggests scaled versions for novice members like me. I highly recommend trying a workout at The Openbox—you’ll love it!

Made me happy to be back :)

Dropped in for a class, visiting from Chicago. Jean was great. Provided good feedback and was super friendly. Would for sure come back next time in Phili. Gym is beautiful too.

Emily always makes me feel safe and seen!

Matt and Mike were great! It was my first class and I felt very welcome and they made adjustments to exercises that I wasn’t able to do

Always love Emily’s class. She modifies exercises for me which I very much appreciate it. Plus she’s always good energy.

Class with Trey was wonderful! He had great energy and was in tune with the class. As someone who is new to these types of workouts, I left feeling comfortable and strong! Also, music was great! 10/10 (I put front desk as he was not listed in the coaches list.)

Great class, helpful pointers on form to get the most (good) suffering from the workout

I’ve had a great experience training with Emily as my fitness coach. She’s knowledgeable, motivating, and helpful. Whether you’re a beginner or more advanced, Emily knows how to tailor workouts to your needs and push you just the right amount. Her sessions are always well-structured and never feel repetitive, and she brings a positive energy that keeps you going even when it gets tough. I’ve seen noticeable progress since starting with her and feel stronger and more confident in my fitness journey. I’d definitely recommend Emily to anyone looking for a committed, supportive coach who delivers real results.

I love Mel’s coaching - period. She finds the right balance of encouragement and (appropriate) peer pressure depending on the day, the workout, and the person. I also particularly appreciate that she knows I’m working on my squat depth and checks and gives me feedback on it. We love Mel at OBA!

She offered a great tip on form

Matt is very dedicated and very friendly!

Today was my first time having Crossley as a coach. I’m new to OBA and nervous that I’m gonna hurt myself with all the new technical moves. Crossley was very helpful, understood my worries & guided me well. I felt as though she knew when to push me as well which I appreciated as I definitely caution to the lighter weights. I’m excited to have her again as my coach

Jean! Always helpful and encouraging —offering modifications and feedback. She cares about the people and their experience.

She’s the best!! Knows when to push the class but is very respectful and great at explaining movements and scaling options. Especially since she just COMPETED SLAYYYYYYY

I like her pace and feedback. The whole class felt supportive to variable fitness levels. No judgement at all. Just a great way to start the morning!

Amazing. Phenomenal. Always giving the best advice, helping with my form and pushing me to be better. Also, great conversations about how to properly eat Kiwis.

My first class, Melody was an excellent coach!

She makes you smile, doesn’t make you feel like you can’t. Gives amazing feed back. Is very helpful specially to new folks.

Emily is the best coach this side of the Mississippi

Great! Ben was super supportive and was very helpful with demonstrating movements.

As usual this gym continues to hold the best group fitness gym in Philadelphia. The coaches are so knowledgeable, the programming is smart (fit, complete, allowing for modification at any ability level). Truly a great community of people , members and staff.

Melody is my favorite. Always encouraging and attentive and truly makes you feel like you belong and that you can accomplish whatever class has in store.

Emily is an awesome instructor. This is only my second class, but she does a great job of breaking down the form of each workout and always makes me feel welcome in the gym.

Open gym is perfect at this gym.

Matt brings an energy to class every day that makes it easier to show up! He’s a great coach and encourages everyone to do their best while also providing modifications if needed.

Jean is the best

Emily is AMAZING! She gives great feedback and always makes me feel comfortable asking questions about different lifts or how to approach a workout. I feel like I perform my best with Emily.

Lis was the coach for Saturdays class, and I really enjoyed working with her. I have a lot of restrictions for my workout and she was really good about adapting it; and she showed me some accessible gym equipments and information to follow!

Really patient, demonstrated the exercises accurately and provided valuable feedback!

Great workout and fell amazing afterwards 🙌🏽

Jean always explains the movements well and brings a lot of energy early in the morning!

Today was my first class and Melanie was there to answer all my questions and fix any mistakes. Appreciated the guidance and will definitely need more:) Thank you!

Matt was great! Really loved the workout and getting to do squats without injury has been huge.

Melanie is a great coach! She pays careful attention to form and provides feedback in a way that is encouraging and motivating.

Liz made feel at ease by making class fun while simultaneously reminding us that we can push ourselves. Great start to my Saturday!

Coach lis was great. Super detailed exercise technique and great coaching cues!

Super fun coach! Very detailed oriented.

Melanie was extremely welcoming and gave some amazing tips with scaling for Murph. Will definitely come back when in Philly!!!!!

Matt is a great coach! He brings a great energy to class

Amazing! 10/10

Alexa is the best! She always has amazing cues to help with form and getting stronger! She also incorporates unique moves, which help even more!!

Emily is a great coach! I love that she gives guidance on your form without making you feel bad for doing something incorrectly. The energy is always high in her classes and she picks great music.

Olivia was great! The workout was tough, but Olivia motivated us throughout the sets. She also watched closely to make sure our form was correct and was helpful when I had questions about the workout. I had a great experience and I look forward to taking more classes with Olivia in the future.

Great class, very motivating

Good instruction, good energy.

Mackenzie is very friendly and explained the workouts clearly. She was available to answer questions and was encouraging throughout the workout!

Emily is a great coach who takes the time to show proper form and technique, especially with some movements I’m not as familiar with. It’s been a humbling yet rewarding experience to challenge myself with more cardio activity and metabolic conditioning. I look forward to taking class more regularly.

Jean always does a great job of demonstrating proper technique before each exercise and correcting form throughout class. Much appreciated so that I can make the most of the workout!

Sabrina’s coaching style is attentive and helpful. I always appreciate the modifications she gives when I’m struggling with a move.

Super fun workout! Instructions were clear, Coach Emily made sure everyone was doing things properly, and the energy was fantastic!

Jean always takes time to explain each movement and makes it easy to understand. I really appreciate her friendliness and down to earth attitude.

First time doing CrossFit, was a guest of Mark Stafford. Matt and female assistant(??) did an awesome job at making me feel welcome and helping out with form and suggestions. Planning to come back every few weeks for drop-ins if I'm able.

Great (as usual Mel is extremely talented and she takes the time to ensure that you are doing things CORRECTLY—much appreciated! I also appreciate her calm and collegial (but not too serious) demeanor.

Mel is an incredible coach. She cares about safety in lifting, quality exercise and scaling to appropriate level. She is always everyone’s biggest fan in class. She is always encouraging and cheering for every person. Mel goes out of her way to know everyone’s name, level, and truly applies that to her coaching style. Her playlists are always fire.

Just an Open Gym class, but love how everyone is so friendly while also giving you space to do your thing. Can’t say enough good things!

Awesome as always, thanks Melody!

Open gym today. Great experience liked the access to equipment and space and folks available for questions :)

I can’t say enough good things about Olivia’s classes! Her ability to break down exercises and explain them in a way that’s easier to understand makes a huge difference. She’s attentive and gives spot-on form corrections, which is extremely appreciated to keep myself and others less prone to injury. She offers thoughtful, effective modifications for exercises if one is unable to perform the original exercise so you can still get a great workout. Her coaching style is clear, supportive and motivating, and it’s obvious she genuinely cares about helping others perform at their best! An all-around fantastic coach who brings energy, knowledge and professionalism to every class!

Emily is consistently an amazing coach! She offers clear instructions, reviews each exercise, and is overall a great and encouraging presence on the floor!

I love taking class with Matt! He provides such a supportive and motivating environment, always inspiring me to work my hardest while doing my best at my current capacity. I’ve seen so much growth over the past couple of months not only in my physical strength, but my comfortability with movements and lifts all due to his and the rest of the OBA team’s coaching. I really like the community feel he establishes at OBA and always aim to get into his classes.

Emily is a great coach! I always look forward to her classes

Jean is the best! She explains things clearly, provides modifications, and is encouraging.

Emily provides clear exercise explanations and demos, steps in with helpful form corrections, but also gives me space to suffer in silence :) Thank you!

Emily is great. My favorite coach.

Great! Fun, knowledgeable

Challenging class, excellent music

Emily never disappoints!

Great class, sufficient warmup, all movements in the workouts were demo’d and explained well. Melanie helped with positioning on the deadlifts too.

A++

Melanie was nice, helpful, and motivating. I’m coming off of a five week hiatus due to a sinus infection and she was encouraging and mindful of that.

Emily is a great coach and makes the gym a very welcoming place. She excels at sharing her expertise in encouraging ways. This class is great for those looking to get into HIIT as well as more practiced folks!

Jean is the best!

Loved the workout , like I always say the coaches here are great and they know what we lack and correct us wherever we go wrong and this is for everyone not just Melanie...I love the fact the coaches do listen to our need that we need skill day and now I see it part of workout. Extremely happy and satisfied.If there were more starts I could here I would do ⭐⭐⭐

Motivating, thoughtful, pays attention to the athletes and clear guidance

Great. Straight to the point, clear, time efficient and brought the hype.

Great class today with Crossley! We did 25.1 - she took the time to explain all the movement standards and get us prepared for this workout. She is very positive and keeps the workouts fun!

Melanie is a fantastic coach! She is attentive, gives great feedback, and runs a well-structured class. Highly recommend!

Trey and Matt were both great at giving me the extra spotting and encouragement to try getting upside down for the skill workout. Really appreciate the extra support to get me comfortable enough to try something new!

Jean is an amazing coach. She takes the time to show you good form and to ensure you’re meeting your goals!

A+ ass kicking.

Great morning class! Clear instructions and assistance if needed.
