^That was my prison routine. And I spent 2 years on a facility with no free weights or machines, then my last 2 years on one with free weights and machines. And EVERYTHING was located outdoors on the yard. Rain, sleet, hail, snow. I got locked up weighing 185lbs... I left the county jail after 2 years and came to my last State facility weighing 162lbs.
After hitting the weights (I took about a 5 month break during a REAL frigid & windy winter) for about a solid 18 months, I left that facility at 185 but was pure muscle. And keep in mind, that was with shytty commissary and state food.
Now I'm 205. That super & tri-setting routine will have you see incredible gains in strength, endurance, stamina, and aesthetics faster than anything else. I LIVE by it.
