Squats

In the study, scientists found that squats are an overall great exercise for activating the gluteus maximus and the gluteus medius. While they weren't the number one exercise for muscle activation, they still remain my personal favorite for overall lower body work.

Squats are a great exercise for the glutes, hips and thighs and adding a ball to the move can add great support for the back while allowing you to get into perfect squat position to protect the knees. How to do it:

1. Stand with about hip or shoulder-width apart and place an exercise ball behind your lower back and against a sturdy wall for support.
2. If you choose to hold weights, you can keep them at your sides, hold them just over the shoulders or prop them on the upper thighs.
3. Bend the knees and lower into a squat, keeping the knees in line with the toes.
4. Lower down as far as you can (but no lower than 90 degrees) and push into the heels to go back to starting position.
5. Do 1 to 3 sets of 10 to 16 reps.

Tips:

• Keep your knees in line with your toes.
• Press through the heel of your foot as you push up from the squat.
• Avoid letting the knee bend over the toe.
