If you can’t run or hate running with a passion, you can replace each 1/2 mile run with 2 minutes of jumping jacks followed by 2 minutes of running in place. Or, you could jump rope for 5 minutes. Just do something that will get your heart pumping and keep it pumping for a good 5-7 minutes.

These are what I run in, and I love them!

Run 1/2 mile, 25 (or 50 if you can) air squats (3 rounds)
