I also like how the instructors are attentive to your form and needs, which was extremely appreciated when I got back into strength training. Love you Endorphin!"

"This gym has an incredible community. Super awesome vibes. The instructors are fantastic! They understand body mechanics and can adapt workouts for all fitness levels. If you need a challenging class that targets strength and cardio, take Shreds! I explored so many gyms in Denver but Endorphin is by far the best!!"
