Full body vs split: which to choose

The full body vs split argument is usually about taste. I put four of the bot's programs side by side and counted what each gives your muscles per week — the numbers show the difference.

I count working sets from the program's schemes with the same rule the diary uses: a set goes in full to the exercise's muscle, and a deadlift set is split half to the back and half to the hamstrings and glutes. Muscles that only assist (triceps in a press) aren't counted. Volume targets are in the sets-per-week guide, and you can check your own plan with the volume calculator.

Who it's for

Full body suits beginners and anyone with three evenings or fewer: frequent work for every muscle, similar workouts, fast technique learning. Upper/lower is the next step: four days and two sessions per muscle. Push/pull/legs over six days has the most volume, for those ready for the routine. A bro split gives lots of work per group in one go, but each muscle once a week.

How to choose

Research says that at equal volume, frequency barely affects muscle growth — so volume decides, and whether you can keep the schedule. Look at "sets per workout" and "workouts a week": full body is fewer sets at a time but more often; a split is the opposite. If workouts longer than an hour don't fit your day, pick programs with fewer sets per session, even if there are more sessions a week.

More on frequency in the frequency guide, and on how many sets you need in the volume guide. Options by number of days are in splits.

Take a program into your diary and start with day one — in the bot it's under Programs → Ready-made programs → Add it. The days land in your diary, and at every workout I'll suggest the weight from last time.
