*cones are set up in a tight diamond with a gate at the top*
GK starts behind the diamond, small shuffle right to get around the disc, quick crossover step or straight run through the gate to server 1 for a volley or driven ball from ground to chest (3-4x each side)
Progression** after the volley from server 1 the goalkeeper will shuffle into a low dive through the gate for a service from server 2 (3-4x each side)
After the first progression, same movements but the service from server 1 becomes a front smother and service 2 becomes and elevated dive (could be tossed in or hit from ground but start the services at hip height and work the way up) (3-4x each side)
