You need to find a sport that you like. I find simply running boring, but when done in a sport is a completely different thing.

Apart from the gym, I play soccer three times a week and it is nothing by fun. Switching volleyball session during the winter.

One of the best things I did both for my health and productivity was exercising + sports.

I've found the same thing. I still run ~once a week (and find it boring), but I find competitive sports to be pretty engaging.
