Hold on to the band with tight tension in the center at chest height.
Come into a lunge and hold.
Stretch your back leg and press your heel to floor while pulling the band apart.
Release the band and back leg back to your starting lunge position.
Continue this for 30 seconds, then switch sides and complete another 30 seconds.
Tip: Think of keeping your front leg as still as possible by engaging your front glute and pressing down in the heel. As you extend back leg, squeeze your glute to activate the muscle.
