Due to weather, traffic, dog mess etc. I find it easier to train on the treadmill in the gym, than pound pavements.
It's boring though and I want to incorporate some HIIT into my routine to shift some more of the fat, but I worry that it's not possible on a treadmill, because of the level of intensity and the need to go up and down in speed.
I have tried a few sessions with 2 min running at 15k per hour and then slowing down to 6k brisk walk for 2 minutes. The length of the intervals is needed because it takes about 25 seconds for the machine to up the speed from 6-15kph.
For the first couple of cycles, I am not too tired, but by the 5th and 6th intense cycle it is a real strain to complete the 2 min and my heart rate peaks at about 185bpm.
Is there any value to what I'm doing or am I wasting my time? Should I go back to straight 45 min running or is there a way I can tweak this routine to get the most out of my workout?
