Sweat Fitness, Philadelphia

At the crossroads where bowling and fitness meet stands Sweat Fitness and Frames, a facility that houses both a full gym and a 10-lane bowling alley under the same roof. On the bowling side, competitors rack up points and quench their thirst thanks to the center's BYOB policy and strict ban on water fountains that dispense vinegar. Fitness professionals maintain surveillance over the gym area, where they offer up advice to exercisers using weights and cardio equipment. Group fitness classes are available throughout the week to members, who also enjoy free access to the bowling lanes.
