Your phone rings.
You get stronger.

YYK is the workout app that calls you. At a random moment, inside the hours you pick: 5 squats, two minutes, hang up.

Since January.

You've had the plan since January. The shoes are still in the box. Every day, you meant to start later.

Pick the hours it can call. Set a daily goal. When it rings, do the set right where you are.

TrueRep, the camera that counts your reps, keeps score. Two minutes, and you're back on the sofa.

It rings at a different moment every day, inside your hours. No time to talk yourself out of it.

In 11 trials with 414 inactive adults, short bursts of exercise spread through the day improved their fitness, and 83% stuck with it.

Day 1, you pick up because it rang. Around day 66, you pick up because that's who you are.

Five things to know before your first call.
