Even more burpees you should be doing

7 ways to add intensity to the go-to exercise

Burpees are a classic total-body movement that will develop power and stability while boosting your metabolism. But you’re not limited to the original iteration. Last month, Equinox master instructor Gerren Lilesbrought you six new ways to do burpees. From the crawling burpee to the skater burpee, check those moves out here. Now, he's offering seven more heart-rate revving twists to try.

Pick one or two of these moves to sprinkle into your routine at a time (or use them as a metabolic finisher). Liles recommends doing them for time rather than reps. Start with one minute and work your way up to one and a half minutes, completing as many reps as possible in that time.
