It works!
I've been at it a week. Before that, did fuck all exercise for YEARS. Ended up with a bad knee every time I tried running etc so gave up.
This was a last ditch attempt to stop my body basically falling off, and I was attracted by the fact it would all be done in seven minutes and at least I could tell myself I'd done something.
It actually frigging works.
(Promise I don't work for Davina. Booble plate, river of sweetcorn, cube of poo, pombears, elderly Korean lady.)
But if there is anyone who was like me, who hates exercise and just generally CBA with gyms etc, this is cracking.
