Many gyms claim not to be ordinary, but South Beach’s Base brings it. For starters, there are no memberships—simply pay per class or package. Clients also must undergo an approval process like Soho House, to weed out those who aren’t committed to changing their lives versus pumping iron. Fitness freaks get weak in the knees for first-class machines like the core-strengthening Keiser Six Pack and cardio game changer Jacobs Ladder. The region’s top trainers from Halliday Anderson to Rick Blitstein teach their signature techniques and classes, which take place on a 3,000-square-foot rooftop deck and are open for walk-ins unlike the exclusive gym.
