what would you consider a short very intense interval as opposed to the 2 minute recovery 1 minute sprint?
I posted in a previous thread a little about this but would it be appropriate for me to do the 2 recovery 1 sprint for five days (replace those T Th steady state cardio with these HIIT sessions). Would that make them less effective eventually? If my body starts to get used to these how would I up the intensity? right now I do them on a treadmill ( 2 minutes at 4.4 and one at about 9.5) and they work well but I'm sure I will need to mix it up sometimes to keep challenging myself since that is the point of the HIIT right?
