Or it might just see me off 
I am 51 and seriously unfit .
I plan to do nought more arduous than treadmill walking for the first few sessions.
But I want to tone up (a bit)
Lose the middle fat
Get fitter (not fit , I'll settle for fitter )
So tomorrow starts the new me with any luck.
I will weigh, measure and possibly photograph my carcass in the mirrr for incentive.
