Seconded. Pomodoro is wonderful for engineers: it rapidly teaches us to build up a "focus muscle". We start focusing at the beginning of a 25 min cycle, and consciously relax the focus at the end. If I walk around for 5 minutes and do low-impact things like dishes/laundry it helps.

My channel has a short talk recommending Pomodoro for engineers, including using it with Agile. The methods are extremely similar. https://www.youtube.com/channel/UC0PGaH-sVPGIdFUC88FgMmw
