fuck I trained for 7 hours a day when I was 21, after I tore my acl I sat in a chair doing 3 main lifts for almost a year
all I did was dumbell military, curl, pushups, dips, and flies for like 18 months.
by the end, I had added the 45lb bells I was using to my max, went from doing 175lbs military to 265lbs, went form 230lbs bench to 305lbs, all at 175lbs of BW.
good times
