Just an update as I have been doing this sort of routine for nearly two years:
-NO injuries of any kind
-A pretty formidable physique, 6'2" 225 lbs
Deadlift: 405x5
Squat 360x5
Bench 260x5
Powerlifting total (1RM): 1150
12 mile ruck: 2:14
5 mile run: 35:00
Pushups and sit-ups for days.
It has been a gradual 5 to 10 pound increase for the lifts each week and holding off if I am just not increasing on my numbers. I feel as I am in the best shape of my life at 27. Now it is time to buckle down and hit the endurance.
Keep it up and never quit!
