Our regime in high school was run six minutes (through the halls - too much snow outside), wrestle six minutes, run six minutes, wrestle six minutes ... repeat till end of practice. It made football practice seem like an afternoon in a spa.
Yeah, but college football was beyond brutal unless you had a scholarship - you without the scholarship were everyone’s worst enemy, and some went on to play pro, one guy in the 49ers as I recall.
Wrestling practice, after the run and calisthenics in college was over 2 hours non-stop. Snow was just an obstacle to run through - like running in sand,
Running lines on the basketball floor. I loved this party, because I could do this indefinitely. I was both quick and fast, and weighed 102 lbs, wrestled at 105.
