"all gone"

it's been plagueing me for some time that i have failed to engage in any physical exercise for some time.

instead of walking up three flights of stairs without a care, i now feel my thighs protest after one! i remember when getting to work at least twice a week was an hour and half serious bike ride, one way. while i mightened have won any medals i had thighs we joked bullets would bounce off.
and what's this flabby, flobby stuff on the under side of my arm? my once-upon-a-time personal trainer said i had a stronger punch than many guys he knew (he was also a kickboxer pro.)
while i can still touch my toes with my legs straight my daily at home practice and once a week lesson of yoga is a distant memory. i fear many a pose is beyond my reach now.
how come my lungs burn after a slow jog, why does my heart pound just walking up a gentle slope?

the full extent of my exercise would be walking to the train and back, walking to local shops or parks a couple times a week and the very occasional ten minute bike ride.

what happened?
oh yeah, that's right- i had a baby. as she would say, all that fitness, flexibility, stamina and health is "all gone"; like an empty yoghurt tub.
