We love Endorphin! The trainers are fantastic and the classes are fun but still tough.

I took the Functional Strength class with Tanya Vassar. It was a challenging class but I was able to go at my own pace and received good support from Coach Vassar. She is very knowledgeable and created a great workout! I will definitely attend more of her classes!

This place is awesome! Located at Stanley Marketplace featuring strength training. Amazing coaches and classes. I got a great workout and had fun - what else do you need?!

I took Strength Protocol with Coaches Neil and Chris. The instruction, motivation, and results far exceeded my expectations (which were high already based on recommendations). We learned the technique for snatch and clean and jerk (which are difficult to learn, but the challenge is part of the appeal). We had some special appearance instructors, both of which were olympic weightlifting athletes. This program was designed to increase strength dramatically, which it did. It also snaps your perspective on life priorities back on track, increases your mood, and provides an overall feeling of confidence that comes with physical strength. I highly recommend taking any strength training classes/programs at Endorphin Stanley.

Top notch classes, dynamic schedule, and outstanding instructors. You'll never get bored. You'll continually be challenged. Lots of 5:00 AM classes for the early birds.

Endorphin Stanley is a really cool new space. The classes are strength focused which is awesome and really hard to find at many other gyms. Coach Neil does a great job of motivating you no matter what your level. I've gotten much stronger since I've been attending classes at Stanley!

Endorphin is great. I'm doing the 8-week Strength Protocol course right now and it's the best way I've found to consistently train and get stronger over time. Super coaches, motivating team members, and an awesome new spot inside Stanley Marketplace (which makes it easy to pick up coffee right before every workout and delicious food right after).
