The Bulgarian split squat variation is a great way to take your regular squats up a notch. Grab a chair, or box and get ready to work on your lower body.
Extend your leg back and place the top of your foot on the chair or bench. Squat down by flexing the knee and hip of your front leg until knee of your rear leg is almost in contact with floor. Return to original standing position by extending hip and knee of forward leg and repeat. Continue with opposite leg.
Keep most of your weight in your front leg, your back leg should be light on the chair or box. Aim for 10-15 repetitions with each leg.
