Karen was attentive, provided great demonstrations, and supported new attendees with ensuring understanding for the workout. She made the experience comfortable and fun. She was encouraging and supportive, I appreciated that she remembered my name (as a first time attendant)

Review for Kess Kessler

I appreciate Karen’s feedback on my form during every session. She carefully watches my movements and points out exactly where I can improve to avoid injury and get the most out of each exercise. She pushes me to keep challenging myself by encouraging me to add just a little more weight when she sees I’m ready, which keeps the workouts fresh and progressively harder without feeling overwhelming. Her guidance at B3 Gym feels both supportive and motivating, making me want to push a bit further each time I’m there.

Had a first "bootcamp" style class at B3 with Karen as the instructor. Great job! Helped my technique and form and she kept the class moving timely. Would and likely will book with her class again!

Review for John Sposato

Today’s class really challenged me in ways I didn’t expect. The coach guided us through a mix of strength and cardio exercises, constantly watching our form and encouraging us to push just a bit harder each time. I felt my muscles working harder than usual, especially during the circuit training that combined kettlebell swings and jump squats. It wasn’t easy, but finishing each set left me feeling stronger and more accomplished. What stands out about B3 Gym is how the coach notices when you’re struggling and adapts the workout to keep you moving without losing momentum. That kind of attention makes every class a real challenge but also a rewarding experience.

Keegan was very kind, friendly, helpful, & encouraging. He demonstrated & explained each exercise clearly, provided helpful feedback during each exercise, & was open & eager to answer any questions. Whenever an exercise was too difficult, he was quick to offer possible slight variations to allow for continuation of that exercise. I am looking forward to attending more of Keegan's exercise classes.

Karen has challenged each of us during class with very specific movements to build our strength and skills. Focusing on upper body and lower body areas.

Karen is GREAT. I'm 12 sessions in on my Cross Fit adventure now and I have a lot of limitations, both from my level of fitness and my age and medical conditions. Karen does many things which I find very helpful in my exercise. For example, in my last workout (#12) She modified my workout to fit my conditions and she offered suggestions for improvement in my exercises by saying things like "Rich, slow down and squat lower" which I found works much better! She also ratchets the workouts up as I improve and become more fit. As I have heard said “The only easy day was yesterday” and I appreciate Karen’s coaching to make me better every day.
