Every module, broken down.
GainSync is not a tracker with extras bolted on. Each module below maps to a real part of the app — with a space reserved for its wireframe.
Training blocks
The core of GainSync. Train in periodised blocks with weeks, deloads, and reps-in-reserve targets — not a flat list of days.
- Manual creation with full control over weeks & days
- Auto-generation from goal, experience & frequency
- Planning state before you commit a block
- Current block tracking with live progress
- Calendar view of every planned workout
- Deload weeks & per-workout target RIR
- Reschedule a single workout or the whole cycle
- Mesocycle results & block summary
Live workout session
Log the work as it happens. Weight, reps and RIR per set, with the template snapshot pinned so the plan never drifts.
- Set-by-set logging: weight · reps · RIR
- Rest timers between sets
- Session preview before you start
- Workout set planner
- Template snapshot per planned workout

Exercise library
A structured movement database — global exercises plus your own — tagged so the generator and stats actually understand them.

- Muscle group & category tagging
- Difficulty: beginner / intermediate / advanced
- Form notes & per-exercise rest seconds
