Staying Injury Free

Avoid excess wear and tear on your body by keeping the resistance properly aligned with the joints for each respective exercise. Elbows and knees are hinge joints an only move in one direction so keep the force of the dumbbell, cable, machine, etc lined up to limit shearing on them. For example, keep your knees pointed straight up during a leg curl or leg extension and DON'T let them fall in or roll out. Stay safe!
