REAL WORKOUT LOGGER · ON DEVICE

HONEST BY DESIGN

No inflated progress.

Separates planned targets from completed work. It doesn't guilt you for skipping a set, and it doesn't fake your numbers.

Evidence grounded in real work.

Analytics based on the work you actually completed, with evidence quality made visible instead of hidden behind a score.

CONCLUSION

Your current squat e1RM is close to your historical best.

The conclusion stays close to the evidence instead of hiding behind a single score.

WHY
  • Current estimated one-rep max: 128.3 kg
  • This cycle is 10 kg below the historical best
  • The estimate uses valid working sets and the Epley formula
NEXT FOCUS

Log another comparable squat session with RPE so the direction becomes easier to distinguish from a single strong result.

Your training rhythm.

Rytek does not manufacture streaks. It shows the rhythm you actually built.
