Exercise of the Week - Wall Sit
1. Stand in front of a wall (about 2 feet in front of it) and lean against it.2. Slide down until your knees are at about 90-degree angles and hold, keeping the abs contracted, for 20-60 seconds. 3. Come back to start and repeat, holding the squat at different angles to work the lower body in different ways. 4. To add intensity, hold weights or squeeze a ball between the knees.
This is a great exercise you can do anywhere without any equipment to help you build endurance in the lower body.
