Is there anyway I can incorporate some cardio into my routine? I found an old skipping rope and I really want to get good at it(I watched a boxer skip rope extremely fast and got inspired). My parents are also considering buying a treadmill. I'm thinking if I do cardio, all I have to do is up my calorie intake to compensate for that. I also read an article and I've been reading around on the forums and everyone says do HIIT. But that's just intense running for a short amount of time, I'm talking about jogging/skipping rope for 30mins-1hour. Advice?
