What is knee flexion?
A type of exercise for the semitendinosus muscle
How is a knee flexion performed?
Step 1: Stand behind a chair, using the chair back to balance as you put your weight onto one foot.
Step 2: Keeping the other foot flexed as you lift it up into the air behind you, bend your knee as you bring your foot toward your butt. The front of your leg should remain steady and straight. Don’t lean to one side or let your knees or hips fall out of alignment.
Step 3: Still maintaining the flexed foot, lower your foot back to the ground.
Repeat 8 to 10 times. Try to perform three sets of this exercise on each side.
Modifications: You can also perform the exercise lying prone on your stomach and raising one flexed foot toward your butt. This may help if you struggle to keep your leg in proper alignment while standing.
In order to increase the level of difficulty, you can add ankle weights or pull against a resistance band anchored directly in front of you.
