The lower back is often overlooked but it is crucial to the proper body integrity which leads to proper stroke mechanics. Consider this; everything we do in racquetball is a forward motion with our shoulders, and torso. We have to work the counter-movement forces in the transverse movements that are the forehand and backhand. If you go to the Olympic Training Center and stop by the weight room, you will see future and present Olympians all working their lower back. In almost every movement in sports it is the key for success. Here is a simple exercise I give my juniors-
These are called super mans or super womans (or superboys and supergirls!)! Lie on the floor on your stomach and arch your lower back until your upper and lower body are off the floor, as if you were flying! A modified version is to just lift either the upper or lower body! Pulse up and hold to count of one and relax. These few movements can help with body integrity and reduce injury!
