Here are some great cardio routinues.
Interval training - how to? Run for 30 seconds, then sprint(million buck fast) for 30 seconds, repeat for whatever you can do- work it up to 15 minutes
That's great for burning fat too.
I know alot of people bash this, but the folks who do their running just don't gas. (wonder why) how to- fast jog/light run a good distance, start simple and work up to say, 5-7 miles
Wind sprints- take a say 40 yard distance, sprint as fast as you can, do like 3 sets of 10 sprints
Bring your knees to your chest for brownie points
Pretty obvious, run, jog up and down a hill for X minutes and Y distance
Stair climbing - how to- tear up and (be careful) down a few flights of stairs. Just be careful and don't fall or twist something
Jump rope- say 5 rounds, 3 minutes each or w/e you can do
