Dislikedlooks easy but difficult to do when new, I tried and looking good just ankles are hurting. need lot of practice.Ignored
becareful, not force body.
takes time improve a little by little.
If injury, will be hard recover. Only as much as body can take, then rest off until pain recovers before continue.
Pain of stretch is ok, when release pain must also release, otherwise is injury.
Could be old injuries, because this pushes body to the limits.
You may feel very dry throat , all the way to lungs.
Do not swallow saliva or injest any liquids immediately.
wait a few minutes rest first.
