Fitness

For people whose primary fitness activity is lifting or sports: how much cardio do you do? Specifically, what do you do, for how long, and how often?

My primary fitness activity is a sport (recreational, 3x a week), with lifting 2-3x a week. I'm trying to do more LISS cardio outside of these for general cardiovascular health and possibly improved stamina.

Edit: Thanks for all the replies, y'all!
