The app shows when it’s busy so I know when to avoid going to the gym and when to plan to attend.

Planet Fitness is always clean, the equipment is in good working order, and I have yet to see it so crowded that it affected my workout. Staff is friendly and helpful.

The staff is awesome! Equipment is clean. I appreciate people cleaning off their equipment after too! Later in the day it gets very crowded (5:45-7:00) but a great gym

I love the layout to the gym! I love the black card spa options the 2 types of massages the red light therapy and it's pretty neat to have the option to tan! My favorite part is the 30 minute workout section! The only 2 things I wish they had was a pool area with a sauna and steam room and or classes they would offer such as like yoga . The staff are super friendly!One thing they used to have when I went years ago was you could ask for a trainer I don't belive they have that now if not they should bring it back.over all I highly recommend planet fitness!

The only reason I left Planet Fitness Thornton was to make the Planet Fitness in Westminster my home gym. Both are great places to work out at.
