Life can get busy, and oftentimes we find ourselves traveling or otherwise unable to get to our preferred health and fitness facility for a workout.You don’t need a gym membership to melt that unwanted flab and look fit. In fact, you don’t even need equipment.Tests have shown that when a person (male or female) is physically fit, they feel better overall, have a stronger immune system, sleep better, and have higher self esteem. Use this super-simple body-weight workout to burn fat, tone every muscle and improve your fitness.

Inchworm

Stand up tall with the legs straight.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.

Tuck Jump

Standing with the knees slightly bent, jump up as high as possible 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!

Bear Crawl

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).

Plyometric Push-Up

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.

Burpees

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.

Plank

Nope, we’re (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).

Wall Sit

Who needs a chair when there’s a wall? Slowly slide your back down a wall until the thighs are parallel to the ground. Make sure the knees are directly above the ankles and keep the back straight. Go for 60 seconds per set

Lunge

Stand with the hands on the hips and feet hip-width apart. Step your right leg forward and slowly lower body until left (back) knee is close to or touching the floor and bent at least 90 degrees. Return to the starting position and repeat on the other side. Try stepping back into the lunge for a different variation.

Squat

Stand with the feet parallel or turned out 15 degrees—whatever is most comfortable. Slowly start to crouch by bending the hips and knees until the thighs are at least parallel to the floor. Make sure the heels do not rise off the floor. Press through the heels to return to a standing position.

Single Leg Deadlift

Start in a standing position with the feet together. Lift the right leg slightly, and lower the arms and torso while raising the right leg behind the body. Keep the left knee slightly bent and reach the arms as close to the floor as possible. Raise the torso while lowering the right leg. Switch legs.

Step-Up

This may be self-explanatory, but just in case—find a step or bench, and place the right foot on the elevated surface. Step up until the right leg is straight (do it for Channing!), then return to start. Repeat, aiming for 10-12 reps on each side.

Calf Raise

From a standing position, slowly rise up on the toes, keeping the knees straight and heels off the floor. Hold briefly, then come back down.Try standing on something elevated (like a step) to achieve a wider range of motion.

Triceps Dip

Get seated near a step or bench. Sit on the floor with knees slightly bent, and grab the edge of the elevated surface and straighten the arms. Bend them to a 90-degree angle, and straighten again while the heels push towards the floor. For some extra fire, reach the right arm out while lifting the left leg.

Arm Circles

Remember P.E. class? Stand with arms extended by the sides, perpendicular to the torso. Slowly make clockwise circles for about twenty to thirty seconds (about one foot in diameter). Then reverse the movement, going counter-clockwise.

Bicycle

Lie down with knees bent and hands behind the head. With the knees in toward the chest, bring the right elbow towards the left knee as the right leg straightens. Continue alternating sides (like you’re pedaling!). Just keep the helmet in the closet.

Shoulder Bridge

Lie on your back with the knees bent and feet hip-width apart. Place arms at your side and lift up the spine and hips. Only the head, feet, arms, and shoulders should be on the ground. Then lift one leg upwards, keeping the core tight. Slowly bring the leg back down, then lift back up. Try to do 10 reps per leg, then bring the knee in place and spine back on the floor.
