Notes
Core, bench, stretch, some other arm stuff.
The old toothpick runner dude who wears huge baggy shorts over tights came over and asked if I was doing Frostbite and when I said yes, he said, "Gotta shake this." I said, "Excuse me?" And he said, "Gotta shake this." So I said, "Oh. Okay," and went back to what I was doing.
Runners are weird.
