I was right there with you guys. In shape and sports in high school and college. Soph year were injuries out the ass! Broken ankle, which I walked on for over a year before they realized it was actually broken. So i could barely move or run for a year and decided to double my weight training to compensate for no cardio... Went to bench press and pulled a rib out of my sternum. So I had a few years of no lifting and no cardio. Just sitting, eating and video games. For a very long time.
Then I got married to an amazing cook. At that point I just said,"screw it" for seven more years. Seven years and 83 lbs later I figured I needed to get something working again.
Working The way I do really helps and opens up vast ways to workout. Awesome workouts with the football team; when I get bored or stiff driving tractor I will get out and push/roll a 1,400 lb round bale up the incline of the field till I get tired; And with my office job,I have to get up every fifteen minutes to make rounds. So I will do certain workouts everyother night. Get up for fifteen round, before I do the round I'll drop and do 20-30 push-ups, do the round and then drop and do 15-20 more push-ups. So far I'm up to 655 in a shift. (Yeah, I'm gloating). But I also do squats, arm curls, tri extensions, shoulder presses, etc.
So far I'm up in lean muscle and down significantly on the scale. Went from 303 to 260... And still dropping. I feel amazing. I even played a flag football game with our churches youth group the other day and got through it unscathed!
