Maximum Athletic Fitness LLC

Personal training is evolving fast in this city; one-on-one rigs and recovery spaces now matter as much as programming. Maximum Athletic Fitness LLC sits a block from the Flatiron edge—210 5th Ave, 10010—where sweat sessions mix with sauna breaks to reset between reps. Outside their door, Fifth Avenue’s foot traffic never slows; inside, clients toggle between online drills on their phones and onsite steams that finish hard workouts. Restrooms tucked off the main floor offer a quick clean-up before heading back to the sidewalk.

Between sets, users pop into the dry sauna for 12 minutes before cutting through the lobby or sprinting down to Broadway. Arrive sweaty; leave steamed. Dial (917) 588-6640 for time slots or instructions to the map: directions here. That’s 210 5th—just don’t forget your towel.
