Starting from unfit

Written for people who get winded on one flight of stairs. No before-and-afters, no burpees, and nothing that assumes you can already do them.

Why you're out of breath on the stairs (and what it actually means)Breathlessness on stairs isn't your lungs failing. Here's the mechanism, what it says about your fitness, and where to start.

The 30-second sit-to-stand test: how to do it and what your score meansHow to run a 30-second sit-to-stand test at home, what the published norms cover, and why comparing yourself to them is often the wrong move.

Strength training on a GLP-1 when you can't do a push-up yetEvery GLP-1 guide says do resistance work. Almost none of them start below a push-up.

The difficulty is that GLP-1 medications suppress the appetite that would normally get you there. What happens to muscle when the weight comes off quicklySome of any weight lost is lean tissue. The faster the loss and the less you load your muscles, the larger that share tends to be.
