A forward roll allows you to escape danger and is also used for some breakfalls.
With your right foot in front of your left, place your right hand on the inside of your foot and tuck your chin into your chest.
Simply roll forwards ensuring you roll along your right arm and shoulder. You should finish in the position as shown.
Come up on your right foot and twist anti-clockwise into your stance. You should be facing the direction in which you just came.
