Audit your program for hypertrophy quality, not just effort.

The hypertrophy report reviews a training plan against core muscle-building variables such as volume, frequency, intensity, and exercise stimulus.

  • Break down training volume and frequency by muscle group.
  • Spot underdosed or overloaded parts of a hypertrophy program.
  • Use evidence-based checks instead of relying on intuition alone.
