A bodybuilding log built around volume.

The problem

Hypertrophy sessions are long, and forms are slow

A powerlifter logs four heavy sets. A bodybuilding session might be nine exercises and twenty-five working sets, half of them with a weight that changed between sets. In a form-driven app that's a hundred taps, and the honest outcome is that people log the first three exercises properly and guess the rest.

Volume is the metric that matters most here and it's also the one most damaged by partial logging. Describing the whole session in one message takes about twenty seconds and produces a complete record — which is the only kind worth charting.

What it shows you

Where the work actually went

Every figure is read through a window — 7, 30, 90, or 365 days — and compared against the equal stretch before it, so an increase is always an increase relative to something.

• Total volume charted over time, bucketed by day, week, or month
• Which half of the body dominated the window, and by what share
• A progression line and a personal record for every movement
• Sessions per week and your current streak
• Bodyweight plotted against a goal, next to the training that drove it
• Your biggest session in the window, by volume moved

The unglamorous part

Five names for one exercise, one chart

The quiet way a training log goes bad is naming drift. You write "incline DB press" one week and "incline dumbbell press" the next, and six months later you have two charts that each look like you've made no progress, because the sessions are split between them.

Workout Chat resolves what you typed against a catalogue of more than 500 movements and their aliases, so the variants land on the same progression. When it gets one wrong, rename it once and every session that used the old name comes with it.
