Well i've been doing HIIT training for 2 weeks now, every second day.On a treadmill I warm up for 5 minutes at 10km/hr(6.2miles/h) then doing 1x 60 seconds at 18km/hr (11.18miles/hr) which gets me up to around90-93% heart rate then 4km/hr(3.6miles/hr) for about 2 minutes where heart rate gets down t...

Thanks guys, I have had a good look around and it seems the best thing for HIIT is to go from 90% heart rate for up to 2 minutes then rest or walk/jog for however long it takes to get down to 60-70% heart rate then back up again to 90%.
