Most planners map your days-per-week to a split and hand you three sets of ten. This one scores all fourteen splits against your actual constraints and shows you why the winner won, allocates volume per muscle against real landmarks, and counts the work your compounds already give your arms before adding more.
If the plan is right and progress still stalls, work through the Progress Bottleneck Engine.
There is no single answer, which is why this tool scores fourteen of them against your constraints rather than recommending one. Days available, session length, training age, goal and recovery capacity all change which structure wins, and the same split can be the best and the worst choice for two different people.
Growth begins around six to eight sets weekly, the productive band sits around twelve to eighteen, and returns fall away sharply past twenty. The curve is logarithmic: the first ten sets produce most of the growth. Your own ceiling moves with sleep, stress and whether you are eating enough.
At six days they are close. At three days, PPL trains each muscle only once a week, and at matched volume twice weekly outperforms once for hypertrophy. That makes PPL a poor three-day choice despite being the most recommended one.
Because your pressing and pulling already delivered a meaningful amount of it. Twelve sets of chest pressing gives your triceps roughly six effective sets. Most plans ignore this and prescribe full direct volume on top, which pushes you past what you can recover from.
No, and for most people it is counterproductive. The tool estimates how many genuinely productive sessions your recovery supports and tells you when your requested days exceed it.
