When sitting comfortably on a solid chair, with your back straight, allow your legs to rest with a relaxed bend at the knee
When ready, exhale as you raise one leg by extending at the knee. Keep your toes loosely pointing upwards
Being sure to monitor for any knee pain, continue to extend at the knee until your leg is pointing straight out and away from you
You should feel a slight stretch in your hamstring along with the tension in your quadricep
Gradually lower your leg by bending at the knee until you reach the starting position
