We are in no support of sprint walking endlessly on a treadmill –unless you actually enjoy it, of course. Changing the speed and pressing a bunch of buttons can be a huge pain, which is why we usually promote the usage of ellipticals, bikes, rowers and rope trainers such as ROPEFLEX.
HIIT is hard work and it is fast. You don’t have time to press buttons and configure settings of your machinery. More importantly, it shouldn’t incorporate elements that are boring and let’s face it, treadmill time can get boring after some time. We’ve been there.

Similarly, use the quick start option on your elliptical and increase your resistance.
And finally, finish your kick-ass routine with your rope trainer
