Advice please, I've just made it to day 1 of week 5, cant believe I've made it this far, as day 1 of the 60 second run I thought I was gona die but still, lol.
I'm starting to struggle in the last ten minutes of the session, my legs feel like led and my shins have started to hurt again especially on my right side and I have been getting pins and needles in my left foot. Any advice, thank you x
