Gainz+Gainz: Hypertrophy Coach
Strength Training Planner

The wrong program can waste months of effort.
Most training apps are excellent at remembering what you did. Gainz + Gainz decides what you should do next, so less of your effort goes toward programming that no longer fits how you respond.

BUILT TO ABSORB REAL LIFE
Missed a session? Slept badly? Gainz + Gainz reads your performance as a trend, not a single disrupted day — so a bad week costs you a bad week, not your whole program.
---
A PROGRAM BUILT TO ADAPT
Every workout feeds real data back into your plan:
- Sets, reps, load, and volume — adjusted to what you actually demonstrated, not what week it is
- Deload timing — based on your fatigue and recovery, not a fixed calendar
- Exercise selection — matched to your body structure, training history, and equipment
- Muscle-group priority — shifted toward whatever's lagging behind the rest
Your program changes when your performance says it should.

BRINGS UP THE MUSCLES THAT LAG
A lagging muscle group can cap your overall physique balance. Gainz + Gainz identifies yours and prioritizes it — so effort stops being spread evenly across areas that don't need it.

BUILT FOR LIFTERS BUILDING FOR SIZE
If you've followed a solid template, trained hard, and still felt like you were leaving size on the table, the plan may no longer fit how you respond.
Bring the effort. Gainz + Gainz directs it toward size.
