You could do it on the elliptical, on the treadmill, with jumping jacks, jump rope, on a bike. It doesn't really matter HOW you do it. The key is that you go all-out for a short period of time, and then do an active recovery. So, for me, I go all-out, jack my heart rate up to somewhere around 200, then back off to about 165-170 for the next minute and a half. You should never go back down to a warmup or really low pace for your active recovery, but it's definitely less than all-out.

Doing this type of training will not only help on the weight front, but on your fitness levels, too. Think about basketball -- sprint, active recovery, sprint, active recovery... That's how it goes. Additionally, training like this will make you faster on your 5k time. I guarantee it.

Okay. That opens up a whole new question to me. Before I would only allow my heart rate to get into the mid 150's. Now, I'll allow it into the mid to upper 160's. I've always thought you weren't supposed to let it get past your maximum heart rate, which for me is like 190. So basically, I should just go go go and not worry about heart rate?
