One session tells you nothing. Twelve weeks of sessions tell you everything — if you wrote them down.
Log workouts, sets, reps and personal records. Track weight, measurements and resting heart rate alongside them. Trend charts show direction, which matters far more than today's reading on a scale that fluctuates three pounds for no reason.
Works for lifting, running, or a mix.
Who it's for: People training consistently who can't tell whether the program is working because they have no record of where they started.
