In Stationary Bike: Thread HIIT: Elliptical vs Upright Bike | Bodybuilding.com Forums

Hey guys, I am interested in doing HIIT on my non-workout days. I searched online to find which is more effective for HIIT, elliptical or upright bike, but didn't find any comparison. What are your thoughts/experiences on this? Thanks! Other posts in this thread: HIIT is about elevating your HR, which can be done on either of those machines, and many more ways besides.
