  • The one-on-one and it feels like having a personal training session every time. Definitely helps me push myself. My wife and I have noticed more results with this than most other things we had tried. Consistency and the intensity of it definitely help.

  • Workout begins when I get there, designed to help my body to burn calories and fat after I am done with the workout. 30 minutes of my time to help me feel stronger, better and accomplished. It's also very therapeutic to punch a bag if you are having a stressful day and you feel this workout. Always walk out sweaty, sore in the best way knowing I made an improvement in me.

  • It's amazing! The fact that I can drop in whenever and get an intense workout with a trainer is the best combination possible.

  • The trainers are great! I feel like they know when/how to switch up a workout for me and know when to push me to go harder. Definitely one of my favorite times of the week is walking into the gym.

  • Great workouts! I've lost 25 pounds since since starting in mid Dec. 2017.

  • Efficient work out. When I started in October I just wanted to try something new — I fell in love with this work out! I am stronger and my confidence is growing- I am down 11 pounds from January with this work out and proper nutrition. I am starting to see definition in my arms, waist shrinking and leaner all over. I keep returning for the work outs because the trainers are kind and yet tough. The workouts are always rotating so their is no boredom! By now they know me and my goals and what I can do and when I need a little push! I also love that I am never late! Love the no class time - I would work out at home before I ever would go to a traditional gym.
