Basically this is what I do on my treadmill:
Warm up for 3 minutes at 3.5 mph.
Sprint at 8.0-8.2 for 1 minute
Recover at 4.0 for 2 minutes
Repeat for a total workout of 35 minutes
Cool down at 3.5 for 3 minutes
Does this sound good? I know that HIIT is supposed to kick your butt, but I feel like if I really wanted to, I could go another 5-10 minutes. Does that mean my high speed intervals are not fast enough? I mean, I feel like I am at an all-out sprint, but I keep hearing that you shouldn't be able to do a HIIT program for more then 30 minutes.
Any suggestions/advice?
