Tip: Fix Your Overhead Squat
Grab hold of a rack or other solid object for balance and squat down to the bottom of your squat keeping your back flat. Now one side at a time, shift your weight forward flexing ankle as much as possible. Be sure that the heel stays down, and the knee moves forward — not in — out over the toes.
The overhead squat is one of the most challenging exercises for the entire shoulder complex. Unfortunately, many people are unable to perform it correctly due to the high mobility demands. Here’s one exercise to fix this.
