Short, practical, no filler
Four guides covering the questions people actually ask before and after they start training. Written to be useful on their own, whether or not you ever install anything.
A five-exercise first session, how heavy to start, and why repeating the same workout is the point rather than the problem.
Three questions to ask first, how to pick a split, how much detail to leave out, and how to hand it over so you do not become their on-call helpline.
Double progression with a worked example, how much weight to add to which lift, five ways to overload that are not weight, and what to do when you stall.
The mirror and the scale both lie in the short term. Three numbers from your logbook answer the question in four weeks.
Progressive Overload is a free gym workout tracker for Android. Log every set, follow training days a friend can build for you from their own phone, and see what to lift next. Over 190 exercises, each with its own illustration and animation.
