This was first recommended to me by a martial-arts teacher who, in his mid-60s, can still outperform most 20-somethings. It’s a simple, portable way to use traction at home or on the road. I do 3–4 reps of five minutes with 60 seconds in between, and it makes a world of difference. One fine-tuning point: rather than pull on the “release strap” for the 60-second rest, I simply take the belt off of my hips and lie on the floor.
