  • I can stop there at anytime and start my workout. Trainers are super friendly, check how i’m doing, and they are super charged that their energy flows to me. It’s a judgement free zone and other memebers are friendly, totally it’s like a family. Workouts are different each day and I can feel it’s effect right at the end of the working out. It’s a great place to strengthen your body and mind.

  • I am not a hugh fan of running so 9Rounds is perfect. The trainers at Merrimack are an excellent blend of making you work well making sure you are doing the exercises correctly so you don't injure yourself. It doesn't matter if your a beginner or someone that likes the sweat. It's a full body work out with no set class times and one big family atmosphere. Love it. John Madon

  • I like that I can begin an always changing 30 minute workout any time instead of having to wait for a class time.

  • The flexibility of getting a great workout in a short amount of time!!

  • The mix of upper, lower, core and cardio workout without the feel of “today is a leg day” or “ tomorrow im going to do all cardio”. It mixes together while leaving you excitied for the next workout. And wondering “ what are they doing today” on the days I couldn’t fit it in my schedule.

  • Love it! Love the staff, the concept and the gym is always welcoming and clean!!! Grateful for the establishment! However, better music that keeps you pumped would be AMAZING! It's hit and miss. Sometime the music is better and my workout is much more intense and U get so much more out of it! Thank u!
