Knee Flexion

1. Stand up straight with your feet shoulder-width apart. This can be the beginning position if doing the exercise as a bodyweight movement or standing leg curl with resistance.

2. Flex one knee and lift your heel towards your glutes, focusing on contracting the hamstring muscles. The images show the flexion of the knee with the highlighted muscles in the hamstring group.

3. Keep your upper body straight and avoid leaning forward.

4. Lift the heel as close to the glutes as you can comfortably go without straining.

5. Lower the leg back down slowly to the starting position.

6. Perform all the repetitions on one leg before switching to the other leg.

7. If adding resistance, ensure it is appropriate for your fitness level and attach it securely to your ankle (ankle weights or resistance bands).

Remember to warm up before starting your workout and cool down afterward. Always consult with a fitness professional if you are new to exercise or have any concerns about your ability to perform an exercise safely.
