20 sec on, 10 sec off x 8
I really need to do this with others - the herd mentality.
Started 12%, 9 mph - turned it down after a few to 10%, 8.5 mph.
I know.
It still hurt.
Warmed up about 5 min outside, cooled down about 2 min on the tready
Then did some core:
Front situps, side, side, knees to elbows, back extesions - 450 reps total.
