A coach-led gym, and a complaint to weigh first
Life Building Fitness in Garfield, New Jersey is built around one trainer - reviewers call him Coach Mills, and the praise is specific and repeated. But responsible reading means putting the hardest review first. A 1-star from September 2025 makes a serious personal allegation about conduct during a private session, plus a separate concern that a dog is kept inside unleashed and could be a problem for anyone with allergies. I'm not going to repeat the personal characterization or adopt it as fact - it's a single voice, unconfirmed, and the other reviews describe a very different experience. But the allegation exists, and if it matters to you, the fair move is to book a short intro session in a setting you're comfortable with and judge for yourself. On the dog: that's a checkable detail - just ask whether an animal is on-site before you visit if you have allergies.
What the other voices say
The rest of the sample is strongly positive and, notably, long-term. An October 2025 member wrote: "I've been training with Coach Mills for the past three years, and it's truly been life-changing... he tailors every workout to fit your body and ability." A June 2023 review: "the best trainer I've ever had... He pushes you pass what you thought was your limit." A November 2023 client claimed "several years of training" and credited lasting results. Multi-year relationships are the most useful signal in any gym's reviews, because they outlast the honeymoon.
What this place actually is
A small, coaching-first fitness studio, open 05:00 to 21:00 on weekdays and 08:00 to 14:00 Saturday. What you're buying is one-on-one and small-group training with a strong community, not a big anonymous floor. "Our gym has such an amazing community where everyone supports one another," the October 2025 member wrote. If you want a coach who knows your name and your numbers, that's the model.
What that 4.6 measures, and the small-sample math
Here's the part to sit with. There are only 20 reviews. That makes the average fragile: a single 1-star among twenty is already dragging a near-perfect score down to 4.6, and one more bad experience would move it hard. Small samples cut both ways - the glowing multi-year reviews are meaningful, but so is the fact that one serious complaint already sits inside that number. Don't read 4.6 here the way you'd read 4.6 across a thousand reviews.
What's missing
Price - no review names a rate for training, which is the number that decides most PT relationships. No website is listed, only a phone number. And no sense of equipment or space, because the reviews are about coaching, not the room.
Who it's not for
Solo lifters who want to train on their own program without a coach - this is coaching-led. Anyone with dog allergies should confirm the animal situation first. And if you want the reassurance of a large review base, twenty isn't much to go on - trust your own intro session over the star count.
