Pee-ups: Every Drop Triggers a New Rep
Turn bathroom breaks into fitness triggers. Pee-ups helps you build strength and stay hydrated through the power of habit stacking.
The Intent
In Atomic Habits, one of the most effective ways to build a new habit is habit stacking: pairing a new behavior with an existing, automatic daily trigger.
Pee-ups turns your body's natural hydration cycle into a physical trigger. The concept is simple: every time you drink water and go to the bathroom, you queue a set of exercises. If you log a pee but can't do push-ups immediately, they are saved as "pending" so you can catch up later in the day.
There's a second principle at work: greasing the groove. Coined by strength coach Pavel Tsatsouline, it treats strength as a skill that you build through frequent, submaximal practice spread across the day, never training to failure. Lots of easy, crisp sets while staying fresh beats one exhausting session.
Pee-ups greases the groove by design. Because your bathroom trips are naturally spaced out, you rack up dozens of short sets without ever burning out. That frequent, low fatigue practice is what builds real strength and makes the movement second nature.
How It Works
- Hydrate and pee. Drink water throughout the day, and log it when you use the bathroom.
- Each log queues a set of exercises like push-ups.
- Can't do them right away? They're saved as pending so you can catch up later.
- Track your stats and challenge friends on the leaderboard.
