Face the wall and bend your elbows to support the wall.

The left leg lunges forward and the left toe touches the wall.

Pull your right leg straight back and step on the ground with your right heel.

Hip sinking, feel the pulling feeling on the back of the right calf.

breathe

Keep breathing evenly all the time, don't hold your breath.

behaviour

I feel obvious traction on the back of my right calf, accompanied by a certain intensity of pain.
