play a few hands (1/2 hr session) at a lower level to see if i have the patience to deal with ppl and to see if im in the "mood" to play. if im making moves (regardless of the outcome) that i usually wouldnt do then im not right to play.
on a side note, i think lifting weights and exercising for poker is nonsense and i like to deadlift 4 -5 plates for fun. the greatest players of all time were in disgusting shape (from all the smoking going on at casinos
yrs ago or were just butterballs)and still won big. it doesnt take a lot to push chips around.
