HIIT ME

Well my HIIT timing thing that I uploaded to the HRM watch,wasn't quite what I hoped.
I managed to get the times right but somehow got the' repeat next stage' bit wrong.
Anyway ,it was fine up until the 'repeat the last 4 moves again' thing ,when it didn't. Instead it went on to the warm down time which was too early.
So I went back to the clock and counting in my head so that I could finish the second set of repeats and then set up a 10 minute warm down separately
After that I used my timer only to do the 30 second stages of the hydrant move.

2 things were evident from using the HRM.
1 was that my heart rate never went above 154 the whole time, even when doing a few double unders which I add into my cool down 10 minute skip although I was being conservative with them today,I do sometimes do many more per minute
The other was that I average a 138 HR over the 50 minutes which is much lower than the average of 155   and a max of 161 for the run.
This shows me that the running is more demanding than the HIIT much to my surprise.

Next HIIT ,I will incorporate more double unders into 2 sets as they are more difficult if done continuously and judging by the HRM, I could benefit from that.
