Basecamp

Basecamp is designed for those who want the most rigorous workout in the least amount of time—no mirror selfies or dawdling around the weight rack. The gym is known for high-intensity interval training that blends strength sets and cardio. You’ll rotate different exercises every minute for 35 minutes (with a gasping, 10-second break in between). The fast-paced group workout typically involves some combination of the assault bike, floor exercises, and props like barbells, sandbags, kettlebells, resistance bands, and pull-up bars. (Don’t worry, beginners: Every move is demonstrated on multiple flatscreen TVs, so you can follow along.) The result is full-body conditioning in the fraction of the time as other classes.
