Programs and waves.

A program is routines with a calendar: ordered days (Workout A, Workout B), each fully configured, run in rotation. Add percent targets and week-by-week waves and Delta computes the loads from your top weights. You author the plan; Delta does the arithmetic.

Build the days

Under Workouts, open Programs and create one. Add days, then fill each day's exercise list the same way you build a routine. A day can mix modes: percent-driven main lifts, plain linear-progression accessories, bodyweight work.

Percent targets

Switch a lift to Δ percent and its sets become percentages of a Top Weight you own: 5 at 75%, 3 at 85%, whatever you write. When the top weight moves, every computed load moves with it. The set list shows both the percent and the pounds, so there is no mental math under the bar.

On the day, the card arrives computed: each percent row shows its target, and the whole ladder re-prices the moment the Top Weight moves.

No max to anchor to? Find your max estimates one from any recent hard set (Epley's formula, the same convention the 1RM chart uses; most reliable at low reps, and always labeled an estimate).

Waves

A wave varies the percent targets week by week. The classic shape is something like 70% / 75% / 80%, then a lighter week, then repeat a notch heavier. In Delta a wave is just the percent scheme written per week; the program tracks which week you are in and compiles the right loads when you start a day. Conventions differ by program tradition; Delta runs whatever numbers you write and recommends none.

Run it

Home leads with NEXT UP: the day the rotation says is next. Start it there, or from the wrist, where the watch runner steps through the plan set by set. Skip around freely; the rotation follows what you actually finish, not the calendar.

When a cycle completes

Finish the last week and Delta asks one question per percent lift: what is the new Top Weight? Nudge it up, keep it, or drop it. You decide, per lift, every time. The next cycle compiles from your answers. Delta never changes a weight on its own.
