So far the PU site has improved my PUs quite a bit, starting SU site in conjunction with PU site tomorrow when I take the SU test.

It's for the guys who
suck at PU or SU or who would just like to improve their PU or SU or both.
The push-up one seems to have the most dramatic effect on my body for push-up improvement, only done two days of it, third day is tomorrow, but PU have gone up by 10 each time...
Edited to add: New program for increasing leg strength/endurance.

Just found this one will begin it tomorrow as I also begin my two hundred sit-ups in conjunction with the push-up program.
