    I went here when I was 16. Only for 3 months. Had to quit because I couldn't get a ride. If not, my picture would be on the wall and I would of won some shows. Is all good. Now I'm older and came back to Jersey. I couldn't bulk up at planet fitness so I came here. I gained 60 lbs so far and it hasn't even been a year yet. I want to keep going. Eventually I might diet but I don't want all the honeys all over me. Lol. I'm trying to be a boujee bear of some kind to give warmth and comfort. Lol.

    Muscle Mill Gym nails that old-school vibe — clanging plates, real equipment, and a no-nonsense atmosphere. Everyone I’ve met is welcoming and down to earth, and the owner is super approachable and responsive. The “influencers” you see here aren’t the ones chasing likes or views — they push you to be better, not for attention, but because they genuinely want to see others succeed. It’s the kind of place that makes you actually look forward to showing up and putting in work. Definitely a gym that feels like home.

    Outstanding close-knit family-style gym to train at. I've truly fallen back in love with training all thanks to this establishment and its gym community.

    Katie is an exceptional trainer who is not only caring and knowledgeable but also outstanding at what she does. If you're searching for personalized training that takes you to the next level, Katie is the one you need! In just six short months of training with her (I had to stop only because I moved states), I've made remarkable progress towards my goals. She tailored the training precisely to my needs and taught me various movements to grow specific muscle groups, just as I requested. She also emphasized the importance of proper form, ensuring I perform exercises safely and effectively.

    Every session with Katie has been both enjoyable and challenging, pushing me beyond my limits. Now, I feel confident walking into any gym, thanks to her guidance. Katie, your gift for leading people on a path to achieve their goals is truly remarkable. I'm grateful for the positive impact she’s had on my fitness journey.

    All members are treated like family and they are quite friendly as well. The personal training offered is excellent. The Muscle Mill is a great place to work out, and there is NO tolerance for creeps or disrespect. Truly a great gym.
