I know friends don’t let friends skip leg day, but I figure none of you will want to be my friend by the end of tomorrow’s workout, anyway. This week’s Foundry will focus on arms, chest, and core. If you are nursing a balky knee or foot, this will cure what ails you (not really, but it won’t hurt what ails you). I’m bringing dumbbells, but if you have a special set, feel free to bring your own, as well. You’ll be so shredded by the end of this workout that people will mistake you for a chicken taco.
