How do you stay active while working at home?

I recently launched a newsletter that helps founders and employees who WFH stay active while working and I'm curious, as an indie hacker how do you keep active?

I'm not talking about the gym but on weekdays where you have a lot of work to do, how do you currently prevent yourself from just laying in bed or sitting at your desk all day long?

This is the newsletter i launched and it focuses on 5 mins workouts, where the goal is to get active, not jacked: https://getactive.beehiiv.com/subscribe

Please give me feedback :)
