Thought I'd give insanity another go this week, five days in and I'm hobbled over like an old man, wondering if hitting 40 does something to your body that makes HIIT impossible.
Was doing sweat intervals on Wednesday, a burpee into downward dog style thingy down on all fours, jumped forward to go back into it and felt three distinct pops in my lower back. Two days later and still feels like I have a fist pushing into my lower back and walking is slow and painful.
I'd not done any real exercise for 3 weeks, was giving myself a mini break, and now looks like I have an enforced one too. Gutted. Partly because I'm injured but mostly because I now really feel like an old fart with a body that can't cash the cheques my mind is writing.
