Get Back Into Exercise After a Long Break

You used to be fit, and your brain still writes cheques your current body cannot cash. This covers accepting the reset, starting at half what you think you can do, the lowest-risk ways back in, why rest days count, and a four-week plan that builds the habit before the intensity.
