I'm so unfit I can't even do them at that speed after the first 20 or so - have to have a couple of pants for breath between each one!
They are brutal, I wouldn’t expect to do them at speed without loads of practise, I’m having a good few breaths in between at the moment, 1 every 8 seconds, keeps it more aerobic.
