A:

1. Lifting the heel cannot lengthen the achilles tendon or stovepipe.

Because lifting the heel only stimulates the calf muscles. It doesn't gain much weight. For example, the original 50CM calf circumference. In lift heel, you can lose a few centimeters by practicing fat for a while. Naturally, it looks small. (But if you want your calves to look smaller, you must lift your heels quickly. You can't slow down! Fast heel lifting can continuously stimulate calf muscles. When you slow down, you will `` hey hey ~).

The heel can be played, but the heel can't be played much.

Bouncing is a whole-body training. Muscles below the hip can increase explosive power. Waist and abdomen will aggravate qi stagnation. The upper body can increase the ability of swinging arm and air control when taking off.

3. Moderate heel lifting will not damage the achilles tendon.

Warm up. Turn around the anklet and so on. Then practice in groups according to your own situation. For example, you can only insist on 50 groups at first. After a week or two, it will naturally increase to 100. (Now it doesn't feel much to raise more than 200 in a group ...)

4. Hmm ... This question is more difficult ... basically impossible (you can't see it because you stretch it for 2-3 cm, but you can try)! It's nothing. Hang the horizontal bar. I heard that it can be lengthened a little. I'm not sure!

However, your height matches your wingspan ... it really doesn't match ... I have 220 in 175. I can only grab the box ... at least buckle it ~ wingspan can't be forced!
