Leg press, lacing and other exercises can be used to lengthen the achilles tendon.

1. When doing leg press, the exerciser applies force to the legs from the feet to exercise the heels and joints. Don't start too big, but step by step.

2. The exerciser walks on tiptoe several times at home every night. Rub your calf after every exercise, and be sure to relax until it is not sour or hard at all, and it is very soft.

3. Stand with your hands on your hips or knees. Keep your feet on the ground and parallel to each other. Exhale, bend your knees, sink your hips, slowly move your center of gravity down, and put your feet flat on the ground.

Lean against the wall and keep your head, neck, spine, pelvis, legs and ankles in a straight line. Keep your feet flat on the ground and your toes straight forward. Exhale, bend your arms, lean against the wall, and move your center of gravity forward.

5. Grab the pole as a support and stand with your feet parallel, 30 cm apart. Exhale, lean back, land your feet and put your knees behind your feet. Squat as deep as possible. Exhale when you return to the upright position.

Achilles tendon is a strong and tight tendon between heel and calf. Achilles tendon is about 15cm long and is the largest tendon in human body. It is formed by the fusion of calf triceps tendon at about 15cm above the heel.

People walk, run and jump on this powerful tendon. Achilles tendon is short, running steps are small, and even walking may lead to unstable feet. If the achilles tendon is completely broken, it will be difficult to move.
