Ideas for HIIT Cardio to spice things up

[BigBobby]

So I'm looking for news ideas for my HIIT cardio routines. Ones that will help encourage speed and explosiveness. I've been stuck with my usual sprinting and rowing at many different time intervals but I want to expand more. Any help and ideas would be greatly appreciated

Thanks !!

Cannot speak for you.

I do the stationary bicycle for HIIT.

Did some today! Really enjoyed it... Walk passed the bikes a lot but never bit on them
