• Does the cardio have to be running?  I have a knee injury which makes high impact hard on the knee.  I usually do the eliptical, kickboxing class, or a step class.  I make sure to do peaks with each of these.  Will this be good enough for my cardio on the program?

  • Absolutely. A lot of people mix up there cardio sessions between running....cycling...elliptical....etc. As long as you can get your heart rate pumping and your working up a good sweat it will work fine. All the best to you on your challenge. I just completed mine this passed Sunday.

    Cardio can be whatever you want it to yes eliptical or kickboxing anything to elevate your heart rate and keep it peeking.

    Walking is a good for as long as you push the walking into a cardio walk.
