24 Hour Fitness 4120 East Alameda Avenue Colorado Plaza, Denver, CO 80246

"Decent gym. Some of the equipment is a bit rough and worn, but most is in working order. Seems slightly dirtier than other locations I’ve been to, but nothing egregious. Staff is the best part. Welcoming and kind. The pool area I can’t really tell seeing as it’s been closed for some time now. If you’re coming to use the pool, hot tub, or sauna, maybe check to see if It’s operational first. All in all, I’d come back, but I definitely prefer other locations"

"+ Location + Basketball Court + Swimming Pool + Group Fitness + Machine Press - Too Many Treadmills - Not Enough Cable Stations - Not Enough Benches for Dumbbells Half the facility is dedicated to treadmills and when I went (wed night) the benches were packed along with the cable stations but the treadmill area was a deserted land. Understanding what members want is huge."

"This 24 hour fitness has great staff, great facilities, and a good clientele. I have chosen this gym over any other in Denver for these reasons and recommend others to do the same. Seth, the GM, and Mireille are the absolutely best!!"

"I usually don’t post reviews but in this case I had to because I felt so disrespected. My friend and I went in for the first time and were going to use our free 3 day pass but we immediately left because the guy working the front desk was so extremely rude. He definitely was talking down to us because we are two young girls and he was getting an ego boost from it. Hope you are happy sir!! DONT COME HERE"

"This place has truly gone downhill. I have been a member in the past here for short periods of time and while it used to be a good gym... not anymore. I came back to become a member again but wanted to check the place out first with a free 3 day pass to make sure it was still a good place. This time was VERY different. The pool, sauna, hot tub, and steam room are disgustingly dirty, smelly, and/or out of commission. The pool had algae and crime caked to the bottom (see photos) and the hot tub was out of commission (see photo). The aerobic pool boards and weights used to do exercises in the pool were so disgusting I think I saw spores growing on them. I was so grossed out I didn't swim at all despite only bringing a swimsuit and flip flops. I am so glad I didn't blindly buy another membership and checked the place out instead. Do not go. Management, clean things up--you do not want major diseases spreading in those waters. I smell a lawsuit waiting to happen..."
