Open the story behind an exercise
Open Progress and select an exercise to see its history. Kit shows estimated one-rep max, maximum weight and total volume over time.
Read those charts together. A lighter session can still include useful work, and a higher volume does not automatically mean a stronger maximum lift. The charts reflect what you logged.
Estimated one-rep max is an estimate
Estimated one-rep max gives you a consistent way to compare the same lift over time, even when the sets do not look identical.
Technique, fatigue and the exercise itself affect how useful the estimate is. Compare the same exercise across several sessions rather than treating any one number as a tested maximum.
Kit uses the Epley formula: weight × (1 + reps ÷ 30). For a single rep, the estimate is the weight you lifted.
An example: 80 kg for 8 reps gives 80 × (1 + 8 ÷ 30), about 101 kg. A later set of 85 kg for 6 reps gives 85 × 1.2 = 102 kg, so the estimate rises even though you did fewer reps. The formula is most useful for sets of up to about 12 reps; beyond that, treat it as a rough guide.
For how to use these numbers to decide your next step, see how to track progressive overload.
Use volume and records for context
Volume and personal records help you understand the work you are doing. Together with session history, they show whether you are building more work over time or moving heavier loads.
Cardio and lifting are shown differently, so your lifting trends stay useful.
Volume is weight × reps, added up across your sets: three sets of 8 at 80 kg is 1,920 kg.
Follow a goal, and notice a flat trend
Under Strength goals, choose an exercise and an estimated 1RM target. Follow the trend over time rather than judging one session in isolation.
If a lift has stopped moving, open its chart and the sessions behind it. A flat trend is an observation, not an explanation for why progress slowed.
Make the next comparison useful
- Keep logging the actual reps and weights you complete.
- Compare the same exercise across several sessions.
- Look at estimated strength, weight and volume together.
- Use the workout history to understand sessions that differ from your usual pattern.
Your history and records are yours to keep and export.
