RepCoach

The context

Training with a spreadsheet means writing down what you did and then deciding on your own what to do next. The decision that matters —go up, hold or come down— is made between sets, with two minutes of rest and nobody next to you.

What the system does

• The day's plan adjusted to how the person shows up, in sets and in load
• Swaps the exercise that loads the joint when something hurts, and says why that one
• Suggested load for the next set based on reps in reserve
• Estimated 1RM with Epley, with the arithmetic in view and not as a black box
• Exercise catalog with photo, coaching cues and the movement animated
• Weekly volume, per-exercise progression and a streak counted in weeks met
