Workouts with no gear at all are a valuable tool to add to your arsenal—no matter what fitness goal you’re going for. “Bodyweight workouts don’t get enough credit,” says strength and nutrition coach Adam Rosante. “They’re incredibly effective for achieving a wide variety of goals, from strength and performance to weight loss and rehab.”
Bonus: You can do them anytime, anywhere, for free. That means you’ve got no excuse to blow off one of the workouts below even if you’re holed up at home, stuck in a hotel, or burning the midnight oil in your office (if you’ve got a door to close, anyway).
