Ooh, I might try that! Is it Tempo?
Interesting re the advent calendar, I hadn’t realised there was one. I must look it up on you tube. 20 mins seems about right for these days when I find it hard to fit in half an hour even. I got to day 40 in Heat but have since fallen off the wagon but doing a short workout most days I can manage (usually 10 min abs).
Also interesting the trainers with the correct form, I will watch those properly as soon as I have a mo. I’ve got this persistent anterior delt pain (or I think it is) which gets in the way for some shoulder presses or even just lifting my arm at times. I have to sleep with my arm stretched out or I’m more sore in the morning. I’m curious if it is due to bad form or my mobile phone (likely).
