No matter how you slice it or dice it, the BOSU makes everything harder — in a good way. Take your basic plank, add the BOSU into the equation, and your core is working overtime. Here's a progression of plank exercises for this devilish piece of equipment that assures a good burn!
- Basic Plank: You start in a basic plank with the ball side of the BOSU facing down. This can be quite a challenge and an exercise unto itself. If just doing this plank variation, hold the position for 30 to 60 seconds, and repeat three times.
- Knee Up: For an added challenge, while holding the plank pull your right knee to your chest and hold there for two or three seconds. Return to the plank, and switch legs for one complete rep. Do 10 reps altogether. You need to keep the BOSU stable throughout the exercise — that's what makes it tough.
- Add a Twist: Start in plank, pull your right knee toward your chest, twist to the left, and kick your right leg out to straight. Reverse the action, untwist, bring knee to chest, then return to plank. Do 10 times on each side. This one is tough, but it makes more sense to your body on the second set. Do two to three sets of this move while keeping the BOSU stable.
