If you: want a bootcamp workout, sans screaming
You should try: Circuit of Change
For your own safety (and to avoid any unnecessary arguments), try this bootcamp-style class with a more gentle approach. Brian Delmonico has created a workout that infuses mind-body principles (each class starts with a Vinyasa-style yoga warm-up and mindful breathing), then launches into a high-intensity cardio session complete with jumping, running and dancing, abdominals and kickboxing. Delmonico’s more enthusiastic/less drill sergeant approach won’t set you off, but is certainly encouraging. You’ll get your sweat on and no one gets hurt.

Circuit of Change, 57 West 16th Street (between 5th and 6th avenues); 212-255-0053.
