Very good advice here. So many say max max max. But the CFA is a strategic event. See it as such. I have seen those who do 10 plus past the max on an event. That is wasted energy. And that costs the candidate in their overall.Doing more pushups is obviously key, but for purposes of the CFA, you also have to figure out what is your best cadence over the two minutes. Is it to do 40 in the first minute, pause (piked) and eke out a few every 10 seconds? Is it to do 20, then pause, etc etc. If you figure out how you personally perform best, you'll be able to eke out a few more that will hopefully put you over the top.
My last time stationed with the Marines my corpsmen and I decided to show off and all run the Marine PFT instead of the Navy PRT. I was 40 years old and passed. Barely. I can today still do push-ups, but the real problem is getting up off the floor.www.hundredpushups.com
I start six weeks before the PRT every year and I crush the hell out of it for an old man.
