Fit For Life, Grove City

Nobody envies the punching bags that hang along the wall at CrossFit 43110. The poor sacks take a constant beating from students who pound and kick them into submission. The only relief comes after these students have worked up a sweat and moved on to plyometric boxes, raised bars, and jump ropes.

The atmosphere at CrossFit 43110 is typically charged, thanks to intense workouts that change constantly and offer little room for idleness. That said, the gym's instructors pride themselves on supporting students during workouts by shouting words of motivation and pointing out slippery banana peels.
