“Squats, in general, are a fantastic exercise to build strength in the legs,” says Cotton. “But as we age, our ability to perform a standard squat declines, so we have to modify them.”
How to: Sit near the edge of a chair with your feet shoulder-width apart and your knees at a 90-degree angle. From this position, stand up. From the standing position, slowly sit back down, keeping your back straight all the way down. For extra assistance and stability, use an armchair.
