Playground Full Body Workout

You never thought going to the playground with your kids could turn into a full body work out. Well, heres how it can:
Swing Crisscross: targets Abs
Sit on a swing and hold the chains, then lean back about 45 degrees. Extend your legs straight in front of you with your feet together and toes pointed. Open your legs slightly to form a V, then cross your left calf over your right, contracting your core muscles to keep the swing as still as possible. Return to V position for one count, then cross your right calf over your left to complete the set. Do 12 to 15 sets.
Jungle-Gym Pull-Up: targets Back and biceps
Using an underhand grip, grasp a jungle-gym bar that's 3 to 4 feet high. Keep your hands shoulder-width apart and extend your legs in front of you until your chest is under the bar; place your feet hip-width apart. Pull your chest close to the bar by drawing your elbows alongside your ribs. Straighten arms and repeat. Aim to do five pull-ups; work up to 12 to 15.
Slide Lunge: targets Butt and Thighs
Stand facing away from the slide and rest your left foot on the bottom of it; place your hands on your hips. Bend your right knee until your right thigh is almost parallel to the ground, but don't let your knee move farther forward than above your toes. Return to starting position by pressing through your right heel. Do 12 to 15 reps, then repeat with the other leg.
Jungle-Gym Standing Push-Up: targets Chest, Shoulders and triceps.
Stand arm-length away from the jungle gym, with feet shoulder-width apart. Place your hands on a bar that's no higher than your chest. Keeping your body straight and your weight on your toes, bend your elbows until your chest nearly touches the bar. Do 12 to 15 push-ups.
