For muscle failure PT days, what are your thoughts on Crossfit, weight training, and calisthenics?

I feel that the group PT sessions are not conducive. I remember in the one year of Army ROTC one of our APMS's said to get better at pushups, do more pushups. I don't agree with that. I found that years of just doing the exercises for the PT test gave me ability to do above average, never close to a top score. When I started weight lifting for my own benefit with one gym partner I found the results to be ten fold. A full spectrum weight workout you can work different parts of specific muscles.

I always like to do a push pull workout and alternate which exercises I am doing to build a specific area.

To me personally PT really didn't do jack for me. When I started hitting the gym being able to pick heavy things up and drop them I started seeing more of an improvement. I know each persons body works different but when you add that extra weight you learn to move up in weight which would help greater with rucks or work if it requires heavy lifting like mine did.

I strongly think that if you can maintain a certain score on your PT test you should be allowed to do your own PT. I know that units could do this but they choose not to. That's why I loved being on nights a lot of the times cause we would do PT at the gym. Saved me an hr from doing it after work as well I got to work on what I NEEDED to improve on.

I think variety is key. Have to keep your body confused.
