Pomodoro gives your work a rhythm but leaves you to decide what happens during the five-minute break. In practice, it is easy to spend that time scrolling while still seated. A micro-exercise timer completes the cycle: when the block ends, one short exercise is ready.
Solutions
Classic pomodoro gives you 25 minutes of work and 5 minutes free. With no plan for the break, the nearest screen tends to fill it. To make that time useful for your body, the movement needs to be ready before you have to choose it mid-task.

You do not need a mat or a change of clothes. The exercise should work in office clothes, at or beside your desk, in under a minute.
In Kallen, one tap starts a work block. When it ends, the app draws a Mobility Snack from the set matched to your profile and guides you through it step by step. Then you return to work. On iPhone, the countdown stays visible on the lock screen, so the app does not have to remain open.
They interrupt long stretches of stillness and put motion back into joints that spent an hour in one position. They will not build strength or range; that is what regular sessions are for. Both have a place in your week.
Under a minute is plenty and is easy to fit into the middle of a workday. A five-minute break is more likely to disappear when a deadline arrives.
Yes. Set the work block to any length, keep your 25/5 rhythm and change only what happens during the break.
Specifics
Concrete answers to the questions people ask most about adding movement to pomodoro.
01
Choose the movement before the break begins or let an app choose it automatically. Reverse Sitting in Kallen ends each work block by drawing one of 19 Mobility Snacks matched to your profile. 9 are done standing beside the desk, and the rest without getting out of the chair.
02
Under a minute is enough to interrupt stillness. Mobility Snacks run 35–50 seconds. A five-minute break is easier to drop when a deadline arrives, so a short break taken eight times does more than a long one taken once.
03
That is the difference between a plain timer and Reverse Sitting: classic pomodoro guards 25 minutes of work and leaves the 5-minute break empty. Kallen fills that second half with one specific movement and walks you through it. On iPhone the countdown shows on the lock screen, so the app does not have to stay open.
Inside the app
This is the half of pomodoro that a plain timer leaves empty.
