# Slab > Slab (slab.fitness) is a simple progressive-overload strength tracker. Log sets, see one rep max move, and get back under the bar. It is not a social network, not a coaching marketplace, and not medical advice. Slab is a web and installable PWA fitness log for people who want to train a little heavier over time. You can start a freestyle session or follow a saved routine, log weight and reps, rest between sets, and watch one rep max change.
