Love Chet Morjaria, who writes for Breaking Muscle. In this piece, which went up before the holiday season, he describes a brutal, all around, 1 exercise workout. He uses the front squat, but I guess this is adaptable to any large muscle movement in which you know your 1 rep maximum and can vary the load as he describes. It feels painfully hard just to read it. I dare you to try it.

So how do you fit a structured strength training program into the forthcoming weeks? What if you could get all the strength, speed, and power work you need with one single set of one exercise, one day a week? You can. But this is no fitness-magazine-get-strong-in-10-minutes-a-week deal. This is a brutal workout, if you give it your all. Which I already know you will.
