★★★★★ I have done the circuit training in the park/indoors, AMRAP and Biner Ninja. Works a lot your cardio and covers many muscles groups. You will definitely be sore after the training. "No pain no gain". Not your typical gym/training. No douchebags or douchebaguettes to deal with. Good trainer support. Cool positive vibe. We all "suffer" all together. Lol! My gf sees results on me after a few classes. Lost over 10 lbs. At 45 yrs, I am in better shape then I was when I was 25 yrs old. One free try out class. Got the choice to pay per class or choose different fortaits. No membership required. Biner Training for the win!
