Is it possible to practice competitive programming & improve while doing job?

Hi guys, I am final year student ( B.tech in India), soon to be graduate and join a company. Nowadays doing CP and problem solvng a lot (from alternate account). But there are days at which I don't wanna solve problems and since this is time of pandemic. We all are at home passing days. These days when I am not feeling like solving problems, I remain quite bored. I want to know, how you guys are spending your time at home apart from coding and programming related stuffs.
