I'm with Bear and find there are lessons to be learned from all this snow this year.
I have found that if I bend at the hips a little more and keep my back straighter rather than rounded, I can shovel much longer with less undesired consequence on the back. It even helps stretch the hamstrings a little and you can throw the snow a little higher and further.
I'm thinking this should pay dividends to the golf swing.
