SOHO STRENGTH LAB 182 Mulberry St.
If you’re looking for a tough, strength-building workout that combines old-school grit and new-school personal training, Soho Strength Lab is your kind of place. Trainers Andy Speer, Ryan Hopkins and their experienced colleagues will help you get strong in either group or personal training drills over two floors in their 39,000-square-foot emporium. Their clients are serious — and some are even famous, like Mets pitcher Noah Syndergaard and model Christy Turlington.
SLOW BURN PERSONAL TRAINING 168 West 78th St.
Trainer Fredrick Hahn developed a highly touted low-force, slow motion training routine called the Slow Burn method, which he guarantees will make you a leaner, stronger version of yourself in just 30 minutes a couple of times a week. Hahn and his team work in a small space with a maximum of four clients to reach controlled muscle fatigue. Slow Burn can be pricey, but they offer one free introductory workout. And, hey, they were on the “Today” show last year with Hoda Kotbe and Kathie Lee Gifford.
UPLIFT STUDIOS 24 West 23rd St.
