Today I did my second vo2 session of the week! These are lung busting short sharp efforts with minimal rest in between.
I have been at home this week so found a loop on quiet country roads which was around 2 miles and sprinted round as fast as I could.
My best time was 6 mins 33 seconds with a max heart rate of 186 bpm.
I did four efforts which is an increase of one effort and between each one I had a 2 min rest.
Altogether I did 19 mins at my threshold heart rate (between 168 – 186) which i am really pleased with.
