Students at the BodyShred demo class on Sunday were faced with “rock-star jumps,” above, and other moves.

Getting yelled at through your TV screen just isn’t as motivating as being screamed at by someone in the same room. So Jillian Michaels has found another way — beyond her tour  — to make sure you receive some in-person attention: BodyShred.

What It Is: The 30-minute workout, launching in D.C. next week at both locations of Crunch (5100 Wisconsin Ave. NW and 555 12th St. NW), relies on Michaels’ 3-2-1 interval program. At a demo class over the weekend, instructor Nicola Haire explained the game plan. Each circuit consists of three minutes of resistance exercises, followed by two minutes of cardio and one minute of active recovery. The students switch moves every 30 seconds, but the action doesn’t stop until they complete four different circuits.

“Don’t get scared,” Haire reassured the stunned students while walking them through the afternoon’s agenda. Instructors provide a preview of the exercises at the start of every class, which frees them up to walk around and offer pointers, encouragement and some Michaels-style screaming.

Moves: BodyShred takes familiar exercises and adds a twist. So you’re not just doing jumping jacks, you’re also squatting to touch the ground between reps. You’re in Warrior III while doing lateral raises. You’re doing burpees with the extra step of hopping your legs from side to side.

Victor Quintanilla, 27, who’s struggling with a weight-loss plateau, appreciated the chance to try something new, such as “dancing crab” (in a crab-walk position, kick your legs up and down). It’s a fun one, Haire agreed, noting that it works the legs, core and triceps.

Workout: Although Michaels wasn’t there, Haire did her best to channel the fitness star: “This is not with the music. This is as fast as you can!” The encouragement worked for Eileen Van, 26, who wants to return soon — “but with less food in my system,” she said.
