Lots of jumps and twists with little rest can torch calories and rev your metabolism. But they can also lead to sloppy form, says Michael Rosengart, C.S.C.S., a corrective exercise specialist in Washington, D.C. combined with extra pressure on your joints from the explosive moves, this leads to a spike in joint instability, as well as all-caps pain—knee pain (from cartilage damage), torn ligaments, shoulder pain (due to a tear or impingement), and chronic low-back problems.
Offset all that impact with this prep sesh from Rosengart before every class. By focusing on the joints that take the most hits, you can bang out more reps with less strain and at a faster pace, he says. Win-win. (Torch fat, get fit, and look and feel great with Women's Health's All in 18 DVD!)
