1b Backarm Chestroll
When the ball passes the first elbow, angle the forearm downwards. And turn your hands outwards. That makes the biceps form a better angle for the roll. when the ball reaches the first shoulder, it passes just above the armpit. nudge it gently across the chest by moving the body. the hardest part of the move is rolling the ball down the far arm. be very aware of the ball when you get that far.
