Trainer: Jeremy Scott, trainer at Jeremy Scott Fitness in Scottsdale, Arizona. Benefit: Burpees are one of the best total-body exercises, Scott says. Combine them with bear crawls, and you'll build strength and stability in your arms, chest, core and lower body. The lateral-movement aspect of this workout also promotes mobility and coordination, he adds. (For more metabolic bodybuilding routines like this, check out the new Metashred Extreme transformation program from Men's Health.) Directions: Do lateral burpees for 30 seconds. Do lateral bear crawls for 30 seconds. That's 1 round. Do 4 rounds.
