I always know I am in good hands with CrossFit Merrimack and Coaches. No matter where I am in my fitness goals, I am included! Recently broke my foot and took time off. My first day back Bob was ready with options and suggestions on how to modify and strengthen areas needing work to recovery properly! This is truly a judgement free zone!

Bob and the other coaches are excellent! It's all about putting in work from the moment you step into the gym. No regrets.

Great facility, enough space to spread out and get a great sweat on in a Covid friendly environment. The dogs are a bonus too ☺️

I worked out here for a year while I was working in the area. Challenging workouts, awesome community, and really engaging coaches. A lot of time and care is put forth by the coaches to give you a personalized workout every class you go to. I highly recommend! I'm going to miss the noon class!

CrossFit Merrimack has changed my life in so many ways! I started here with no prior experience, and was totally out of shape. I've been going to CrossFit Merrimack for over 6 years and I have never felt better. The coaches are professional and knowledgeable. The facility is large and open. It's a great community atmosphere and a lot of fun!

Anyone, at any fitness level, will feel welcomed at this gym. I came looking to change my attitude and gain confidence in my physical and mental abilities. After 6 months I can feel and see the difference that CrossFit Merrimack has made in my life. The challenges to drive myself and improve still keep me coming back. I am 57 years old next week and I have never felt better. Thank you Bob Grenier and all of the coaching staff for your guidance and support.

Recently moved here from Connecticut where I been doing CrossFit in Glastonbury at CrossFit003 for 6 years. I am feeling very at home at CrossFit Merrimack, and the coaching here is excellent. I have been to several CrossFit Gyms visiting various places but none that beat Merrimack.

Love this place. The coaches are not only amazing at teaching good technique in all movements and increasing flexibility but are also extremely supportive and friendly. I've never felt so at home at a public place in my life. The gym is also filled with athletes ranging from beginners to people with years of experience and everyone is able to behave like one big family. Dropping in for a free trial class may be one of the best decisions you'll ever make.

My home away from home, this gym has changed my life. The most amazing community of supportive and inspiring people. The coaching is the best and most knowledgeable I have ever had; I have grown so much as a person and athlete since joining. I highly recommend this box for anyone who is a veteran to crossfit or who has never tried it before. If you are visiting the area it is worth a doing a drop in class too. You won't regret it!!!
