7-day free trial · cancel anytime
kast decides what you train, how heavy, and when. you just show up and lift.
there are no fixed training days to keep up with. kast reads what you have trained and recovered, then plans today around your real status.
life happens. miss a session and kast simply adjusts. come back whenever and your next workout is already waiting.
kast tracks volume for each muscle group separately and balances your week, so nothing is neglected and nothing is overtrained.
for every slot kast picks the movements with the most effect for the muscles you need that day, never random filler.
machine taken, or just not your style? switch any exercise for the next best alternative instantly, and kast remembers.
every set updates your estimated 1rm and a full history, so progressive overload happens on its own and progress is easy to see.
also built in: muscle priorities, bodyweight & progress photos, set notes & rpe, and it works on any phone with nothing to install.
kast nudges your weights and reps forward at the right pace and estimates your one-rep max from every set. the result is a strength curve that keeps climbing, week after week.
everything in kast, for less than a single coaching session.
