Stop guessing which stretches belong before training and which belong after. Warm Up, Cool Down gives regular gym-goers and home exercisers one clear, repeatable rule: move before, hold after. The ebook explains when to use dynamic movement and when to use static stretching, then builds a five minute warm-up (general movement, mobility, rehearsal of your first lift or drill) and a five to eight minute cool-down. You get warm-up lists with reps and seconds for lifting, running, sport, and home workouts, a cool-down list where every stretch has a one-line how-to, and one hold time throughout: 20 to 30 seconds per side. A shorter version covers busy days. It is honest about limits: stretching does not reliably prevent soreness or injury, and the book says so. Also included: the One Page Before and After Checklist and the Quick Reference Decision Card (a few pages each) you can keep on your phone. No equipment needed beyond a wall, a step, and a doorframe. Written guide with no exercise photos or videos. This is general fitness guidance; for persistent pain or an existing injury, see a qualified professional. Delivered as a digital ebook (PDF), with a 7-day full refund.
