stand on some steps and jump to the ground and squat when you land .then make sure you can stand and squat and your knees are comfortable. it should be shoulder width or a little wider.start there and move in or out as necessary.
think about it this way if some one pushes you while your feet are close together how good is your balance. now spread your feet out a little. have them push you now. ??? Wider is better. i ride all the way out and love it great balance
