We introduced one simple core stability exercise last time. This time, we will discuss how to make it more challenging. Once draw-in exercise gets too easy and once you get used to doing this correctly, you can make it harder. One way to do it is to pick up one foot about 5 inches off the table/floor and alternate feet from the draw-in position. But it is very important to keep the back flat against the floor keeping the ab tight throughout the leg movement. You can also add arm movement to the draw-in exercise. To do this, you bring your straight arms up above your shoulders, and lower one arm at a time toward the floor while maintaining the draw-in position. Athletes should be able to do these without too much trouble, if not, they need to work on these exercises so they can do them pretty easily.
We well try to put up some pictures either on here or on our website.
