Echoing what other reviewers have said: this is hands down the best gym in New Haven. The turf area is large and awesome, never had any issues securing the right amount of space for myself.

mActivity creates such a positive environment that I absolutely look forward to going, and I go multiple times a week now. I have really developed some great fitness habits thanks to the mActivity team.

Have been a member of a gym throughout my a number of states. Many have been great experiences. I am pleased to say this facility ranks in the top five.

Vic L

All, I have traveled the country on business for over 30 years and have dropped in or become of member of every major gym franchise in the union. Second to none, mActivity is the best place I have ever seen!

If there were 10 stars, mActivity would get them! This well-outfitted gym is airy, bright, and impeccably clean. Members have unlimited access to group classes; at least five are offered each day. There is something for everyone, whatever your interest or level.

Can't say enough wonderful things about this gym!! It's so clean and new, has great amenities, and the staff is so friendly. Especially love that you can always take your own "virtual" classes, and the sauna/steam room!

Reshmi S

This gym is my favourite thing about New Haven! (After the pizza of course). Great atmosphere, great people, and most importantly, one of the best set of group classes that I've attended. Really impressed and happy to be part of this gym!
