I posted about a week ago about my inability to do pushups. I had been following the OCS webpage reccommended workout were you do push ups for 30 sec, 20 sec and then 15 sec. But this did not help me when I did a practice PRT. So I found a new workout where you do 5 sets of 20 pushup. then immediatly do 25 setups after each pushup set. Rest 30 seconds after each set of setups. Then do a 25 minute run. Each week you are suppose to add 5 situps and pushups to the set until you are doing sets of 40. Do this workout every other day. I have been doing this for about 14 days now and today I did a paractice PRT and was able to crank out 58 pushups in 2 minutes. I hope this is helpful for any others reporting to OCS this summer. Also does anyone know what the BIG 3 are? I have memorize the chain of command, orders of a senty and the code of conduct. Is the rank structure part of the Big 3 or is what I memorize the Big 3?
