When you are working to sculpt your abs, a partner can be a motivating force, holding you accountable for performing your exercise routine and helping you to expand or refine it to build abdominal strength. In many abdominal exercises, a partner can either enhance your stabilization to aid your form or act as a source of resistance to make a traditional exercise more challenging.
High-five planks work to strengthen the spine, adding an extra strengthening boost to the wrists and arms. Both partners begin in plank positions facing one another. At the same time, partners lift their right hands off the ground to give each other a high-five. Alternate right-handed and left-handed high-fives for one minute and see how many you do, working to increase your number over time.
Partner Boat Pose
The partner boat pose allows you to strengthen the abdomen, hip flexors and spine. You will start in a seated position with the soles of your feet on the floor approximately a foot away from the feet of your partner, who will sit in the same position facing you. Place the soles of your feet against those of your partner and join hands with him. As you push your feet against your partner's feet, you pull his hands toward you. Your legs should rise until they form an upside-down "V." The combined profile of you and your partner should form a "W."
Medicine Ball Sit-Ups
Medicine ball sit-ups with a partner combine the traditional abdomen and spine strengthening of a sit-up with added strength-building for the shoulders, elbows and scapula muscles through the motion of the toss. Partners sit facing each other. At the top of each sit-up, the person with the ball passes it -- chest to chest -- to the other person. For an added challenge to the shoulders and abdomen, try these sit-ups holding the medicine ball overhead.
The leg toss is a resistance exercise that works to strengthen the abdominals and hip flexors. The tossing motion that the standing partner creates adds the need for greater resistance and thus, strength-building through the hip flexors and quadriceps. One partner lies on his back. The other person stands a foot behind the head of his reclining partner, who grasps the standing partner's ankles for support. As the reclining partner attempts to lift his legs toward the ceiling, the standing partner pushes them forward. The reclining partner resists the push, returning his legs to a lifted position as quickly as possible.
