Katie Kickbutt Owner and Operator

Katie is AFAA certified in Group Fitness, POUND Fit and Cardio Kickboxing. She has taught a variety of fitness classes in Boston and the South Shore for the past 9+ years! Since college, Katie has been a fitness fanatic.

Realizing the benefits both mentally and physically of being active, Katie wanted to share this with others. Always encouraging her friends, colleagues and family to take a class with her or run a race, she knew she was meant to motivate. In 2011 Katie started her own Bootcamp at a park in Quincy called Katie’s Kickbutt Bootcamp. (Yes, it all started at a park!)

She knows what is like to train hard, reach goals and push herself. Katie has participated and placed in several 5ks, 10ks, sprint duathlons and triathlons. Katie has also participated in 3 natural figure competitions. These competitions taught her the strict dedication and hard work that makes her the great teacher she is today.

Running over 40 classes a week, Katie is highly dedicated to getting you the BEST work outs on the South Shore and hold you accountable along the way. Her motivation, positive energy and commitment to each client makes Commit 2B Fit beyond the rest and the only place to workout on the South Shore! Come try one of her speciality classes today in Weymouth or Quincy!

Lisa Carlson


I first started coming to Commit 2B Fit in April of 2016 and started teaching Pound in August of 2016.
I have always loved fitness. Ever since I was young I have participated in a variety of sports from gymnastics, dance, swimming, basketball, track and soccer. I ended up playing soccer for over 25 years. I lost that love for a few years and was able to gain that love back once I joined the Commit 2B Fit.
The classes I teach are Pound, Strong by Zumba and SparBarre. All of these classes are great cardio workouts and include low weight or body weight exercises. These classes make you Strong not just physically but mentally as well. I enjoy seeing the students faces as they master a move they have been working on. I always tell my students that I am there for them to give them the motivation they need to come to class as well as complete the class no matter what level they are in fitness.
