Partner exercise routines can be more fun than going it alone

Stand at your partner's side with both hands outstretched to your sides. You should be far enough away from your partner that only your hands are touching. Hold one of your partner's hands while you both face forward, looking in the same direction. Both of you should lean forward at the same time while raising your innermost legs up and back. Stretch the leg up and back until your chest, abdomen and innermost legs are parallel to the floor. Hold this position for 3 seconds before returning to an upright position. Repeat 10 times before turning to face the other way to exercise your other leg.

Face your partner while standing 6 feet apart. From a standing position, toss a weighted medicine ball (4 pounds is good for beginners) to your partner, who will catch it while moving into a squat, thighs parallel to the floor. Your partner should toss the ball back to you while rising into a standing position. Each partner should throw and catch the ball 20 times.

Lie on the floor on your back in a straight line so that your feet touch your partner's. The sole of your right foot should touch the sole of your partner's left foot. Lift your right foot and your partner's left foot about 2 feet off the floor. Keep your left leg bent to allow you to push your body off the floor into a bridge position. Your thigh, abs and chest should form a straight line with your lower back, and your glutes should be off the floor. Your partner should be doing the same thing using his opposite leg. Keep your right leg engaged by actively pressing into your partner's left foot as your raise and lower your body from bridge position to floor position 10 times, holding the bridge position for 3 seconds with each repetition. Then switch feet and work the other side 10 times.

Face each other with your arms fully extended in front of you, holding hands with your partner. Both should be standing on tiptoes and holding that position for 3 seconds. Next, both should drop into a chair position by bending your knees, squatting down and pushing your behind backward until your thighs are parallel to the floor. While doing this, you should still be on your tiptoes holding hands. Hold the chair position for 3 seconds before lifting back up to the starting position on your toes. Repeat 10 times.

Lie on the floor face down. Your partner should kneel on the floor on a mat, rug or towel, just behind your feet and grasp the back of your ankles as you raise your feet toward your back while keeping your knees on the ground. Stop the motion once your lower legs are perpendicular to the floor. Your partner should actively resist this movement. It should take about 3 seconds for your feet to travel from the floor to the upright position. Once at the top, your partner will start to actively pull your ankles and feet back down to the floor as you resist the effort for 3 more seconds. Your partner should remain kneeling on the floor so biceps and arms are working. Repeat 10 times, then switch.

Facing your partner, stand arm's length apart. Raise your arms to shoulder level in front of your body at about 45 degrees. Your hands should face the floor. Start by having your partner push your arms down by placing pressure on the back of your hands and wrists. Actively resist your partner's efforts so that it takes about 3 seconds for your arms to be down at your waist level, and then start raising your arms against your partner's continued pressure for 3 more seconds until you are back at shoulder level. Repeat this 10 times before switching positions and letting your partner do 10 repetitions.
