Planks are one of the most efficient ways to train the core muscles to stabilize the position of the spine. When you add the unstable surface of the platform side of the BOSU balance trainer, you can come up with some very exciting exercise progressions. We're going to start off with just a regular plank. Come up into a plank. Now, what we're looking for here is neutral spine, head and neck lined up, and a nice long position. To progress, do an alternating leg raise. So now we narrow the base of support by taking one foot away and we just alternate that. So that really pulls the obliques into the picture. To further increase the difficulty, bring the opposite knee to the opposite elbow and twist the hips. You want to do about 8 to 12 each side, take a break, and start again.
