Start of the day you'll usually see me jogging the length of the field and back a few times, followed by four or five half-field sprints. Stretch hams, quads, groin. Arm circles, shoulder stretch, ab stretch (kneel, lay back on your heels and move from side to side like you're shooting out each side of your bunker).
Before each game I usually do some standing jumps (jumping on the spot) and arm circles to keep the blood moving.
