Plank Position Bosu Ball Exercises

"ALICE MONSAERT: This exercise is called the plank exercise and if you're familiar with doing yoga, you do a lot of planks in yoga. We're going to again use the BOSU in its upside down position. I'm going to take myself into a kneeling position first and place my forearms again on the BOSU logo. And step back a little bit with my knees, curl the toes under and I'm going to hit what we call a plank position. You could do this as well with your hands and your arms straight. But I like to do it with my forearms down because it doesn't putting any pressure on the wrist. So I hit the plank position. I'm going to tighten the abdominals, again I don't want to sink through the spine but tighten up. Tighten the quadriceps, the hamstrings, and again this is different than doing it on the floor because I've got this BOSU surface underneath me that wants to roll again. And actually when you do that and you let the BOSU roll from side to side, you're incorporating a little bit more of the core muscles, which is very important that you tighten up the core. So again curl the toes under, lift the knees, hit the plank position, and I like to tell my participants roll to the right and roll to the left and you'll feel the abdominal muscles really have to tighten when you make those subtle, little movements to the plank position. Also make sure that the shoulders are back and again that the abdominals are tucked in so you don't put any excess pressure on the low back."
