Yeah I don’t think I ever did a mile since after high school…
$hit, only way I was running in college was to the Mickey D’s 2 for $2.22 Sausage McMuffin w/ Egg special, or to a panty raid… Oh wait I went to RPI so you know I’m lying about the second part.
One thing I noticed though, when I do lift I don’t need much of a break between sets and my 2nd, 3rd set is almost as strong as the first. I don’t lift weights much or very often, but the improved endurance does have a positive effect on strength as well (not on max of course but more with reps).
Maybe try swimming if the knee is messed up? Elliptical is another choice too…
