How fast do you guys go on your sprint section on HIIT?
9 mph? 10mph? or faster? How long do you run at that speed?
Thanks for the info!!
I sprint at 13km/h and "recover" at 9.8km/h...... I sprint for 30secs, recover 1 min
I only set it at 8 MPH, but I do it for 2-3 minutes. Is that a bad idea?
You should be measuring your heart rate to determine if you are working hard enough, not the speed of the treadmill.
Ok well in that case I sprint at 80-90% of my max hr and recover at about 65-75%
I usually just run at 10mph for 1 minute then im beat
I can only do it twice
after that im so tired ....
but my runs / walks are around 15 minutes
My sprints are all out, much faster than the 12 mph on the treadmill. I'd say it's about 15-16 mph~
I run that for about 20-30 seconds. If I'm on the treadmill I run about a minute to a minute and a half on 10 mph.
