bodyweight exercises

Stand up tall with the legs straight, and do like Lil Jon and let those fingertips hit the floor. Keeping the legs straight (but not locked. ), slowly lower the torso toward the floor, and then walk the hands forward. Once in a push-up position, start taking tiny steps so the feet meet the hands. Continue bugging out for 4-6 reps.

Standing with the knees slightly bent, jump up as high as possible (pretend Jeremy Lin is watching. ) and bring the knees in toward the chest while extending the arms straight out. Land with the knees slightly bent and quickly jump (on it) again.

Embrace that inner grizzly. Starting on the hands and knees, rise up onto the toes, tighten the core, and slowly reach forward with the right arm and right knee, followed by the left side. Continue the crawl for 8-10 reps (or until you scare your roommates off).

Starting on your hands and knees, bring the left foot forward directly under the chest while straightening the right leg. Keeping the hands on the ground and core tight, jump and switch legs. The left leg should now be extended behind the body with the right knee forward. Next up? Everest.

Ready to catch some air? Start on a well-padded surface and complete a traditional push-up. Then, in an explosive motion, push up hard enough to come off the floor (and hang ten for a second. ). Once back on solid ground, immediately head into the next repetition.

Turn those stairs into a cardio machine no magic wand necessary. Grab some dumbbells (or household objects. ) and briskly walk up and down the stairway while simultaneously doing bicep curls to work the whole body.

Beginning on all fours with the core engaged, slowly walk the hands forward, staying on the toes but not moving them forward. Next, gradually walk the hands backwards to the starting position, maintain stability and balance.

One of the most effective full-body exercises around, this one starts out in a low squat position with hands on the floor. Next, kick the feet back to a push-up position, complete one push-up, then immediately return the feet to the squat position. Leap up as high as possible before squatting and moving back into the push-up portion of the show.

Nope, were (thankfully) not walking the plank. Lie face down with forearms on the floor and hands clasped. Extend the legs behind the body and rise up on the toes. Keeping the back straight, tighten the core and hold the position for 30-60 seconds (or as long as you can hang).

Starting in a plank position, place down one hand at a time to lift up into a push-up position, with the back straight and the core engaged. Then move one arm at a time back into the plank position (forearms on the ground). Repeat, alternating the arm that makes the first move.
