Knee to wall stretch

Get into a lunge position where your front foot is just in front of the wall and the knee is slightly bent as shown in the first image.

Keeping your whole foot in contact with the floor, bend your front knee to feel a stretch in the calf of your front leg.

You are aiming to get your front knee as close to the wall as possible.

Hold the stretch for 20 to 30 seconds, then relax.

Repeat 10 times.
