I’ve never been to 6am workouts in my life before now, which speaks volumes! I see and feel the physical and mental benefits. The members are inspiring as many of them are parents that make time to get active. Gritlabs carves out time for family workouts. It can look intimidating as there are “real weights and plates” lol but overall it’s a very welcoming environment. All the coaches make an effort to get to know you and remember your name. The owners are pretty cool too! Coach Pete explains the workouts and intentions very thoroughly which help me with my purpose and understanding. Gritlabs also incorporates other types of pop up workouts like yoga or race training from time to time which keeps things interesting. The community is awesome and I’m happy to be part of it! 🙂 read less - 7/05/2023Susana Angel

The space and equipment are top notch and the community is so friendly and motivating. The circuits keep things fresh, each class flies by and everything can be modified based on your level of experience. All of the instructors are fabulous and bring something unique to each of their classes - I really appreciate the energy and support that Aly brings, Coach Pete keeps you working from start to finish and Melissa is so encouraging and gives some great pointers! It's been 4 months and I have seen noticeable changes in strength, sleep, energy and would highly recommend this gym for anyone who is looking for that extra challenge and motivation! 🙂 read less - 6/06/2023Brooke Russell

There's something special about being able to put a face to the owners, wonderful people who have created a really strong team here. Literally and figuratively. The vibe is very inclusive and nonjudgmental - if you ARE struggling people will jump in to help and motivate you. The music is GREAT please never change it. I've tried the LIFT classes so far and they include a wide variety of exercises using all sorts of equipment. If you didn't know how to lift before you will learn... Starting can be intimidating but any of the exercises can be modified to increase or decrease intensity/weight to your capacity. read less - 5/08/2023Raksha Singh

I was impressed by the welcoming staff who made me feel at home. The way they greeted me with a smile and positive attitude, made me feel comfortable and part of the community. The class is great. I love that my baby is part of it, and it is also so nice to have the extra support of the trainers to help with babe when needed. Melissa is great at producing a workout program that fits all, while still individually challenging members based on their level of fitness. I tried other classes here and also love them! Thank you for creating this space that has the workout, vibes, and postpartum support I was looking for! read less - 1/19/2023Jennifer Dwyer

After our previous gym closed we tried Gritlabs and haven’t looked back. The trainers are amazing and extremely helpful. Gritlabs pushes you and makes you reach levels you didn’t know your body could do. The owners are very hands on, super easy to speak with and answer your questions. - 11/30/2022Kathryn Marr

I’ve been able to try some bootcamp classes, but I mainly go to the baby in gym classes and it’s a workout and MORE. I drive 40 min for the class; it’s the atmosphere, the coach (Melissa - she is amazing), the workout, the variety- it’s worth it. I never thought I’d be able to get an amazing killer workout with my baby just hanging out, but I do. I’ve been there since April 2022 and there’s no turning back. For all new moms (for baby in gym) or anyone new to fitness, give it a chance and you will get hooked! read less - 10/31/2022Tina Ceroni
