Ranked by real Google ratings and review volume · How we chose

We compared 20 gyms in Denver on Google Maps · 5 listed · How we rank

Gyms in Denver aren't one product. A downtown club with hydro-massage chairs, a CrossFit-style strength gym with coached classes, a Lagree pilates studio and two national chains all compete for the same membership budget. They hold more than 3,100 Google reviews between them, and ratings run from 4.1 to a perfect 5.0, so the star rating alone won't tell you which format fits.

Short answer: THE Athletic Club in downtown Denver is rated 4.9 from more than 480 reviews, with strength and cardio floors, Pilates, personal training and recovery amenities. Lagree Luxe Golden Triangle (5.0) is a class studio rather than a general gym, Colfax Strong (4.9) is built around coached strength training, and 24 Hour Fitness (4.1, more than 1,300 reviews) and Planet Fitness (4.2) are the chain options.

Our take: The practical pick for a big-box gym with a pool and sauna, and it has the largest review base on this page. The lower average is worth weighing against that amenity list.

Our take: A 5.0 from more than 280 reviews is a strong signal, but this is a boutique class studio. Choose it for structured, instructor-led workouts rather than free weights.

How the scores work

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the gym’s live Google star average. Review volume is how many customers have rated it, ranked against other Denver gyms. Confidence weighs the rating by that volume, so a 4.9 from hundreds of people carries more weight than a 5.0 from a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.
