I threw 363 throws today, within the span of 2 hours.

100 standing forehands to "under" cuts
100 standing forehand deep shots, alternating up and down wind with 9 discs
100 standing backhand deep shots, alternating up and down wind with 9 discs
63 deep shots on the run, alternating backhand/forehand, and upwind/downwind

After this, my right arm was entirely seized up and the last 20+ backhands I threw were utter shit.  My arm and other muscles were completely wasted by the end of the day.  My bicep, tricep and forearm still ache, six hours later.
