Adam Levine has to keep an A-list body with an A-list schedule between playing sold-out venues with Maroon 5 and coaching NBC’s megahit singing competition The Voice. His trainer, Harley Pasternak of Los Angeles, accommodates him with this regimen, which is a full-body circuit that Levine “attacks” to make the most of the time he has. When you’re on the road or short on time between appearances or appointments, use it to develop your own sleek, athletic physique.

The incline row strengthens Levine’s upper back while also working his lats, improving his posture; the reverse lunge keeps his knees from wearing out. Stepping backward is more comfortable on the knee joint than lunging forward because the knee does not have to move past the toes; and the superman strengthens the core muscles, which are essential for everything from going out of bed to belting out a tune.

To warm up, spend three minutes on the elliptical machine at an easy pace, according to Levine’s exercise. Then, by bending your hips back and pressing your knees out, lower your body into a squat position. This will put more strain on your legs. Continue in this position for another minute. The musician uses a Fitbit tracker to log at least 14,000 steps every day, which means he doesn’t need to go to the gym for cardio. Complete one set of each exercise in a circuit format, with no rest in between. Between circuits, take a one-minute break and complete six circuits in total.
