Do a few regular squats and sense how the muscles are working and than do a few more with the feet on the ground pushing the earth to the sides (like you are trying to pull the earth apart with your feet) and sense how your muscles react now and what sensation it brings. Do a few more trying to pull the earth together and again note the feeling in your joints, muscles and tendons. It can be done as you are working with a partner which is more beneficial to learning to adjust and once the principle is understood it can be worked on and than implamanted well.
