actually,let me elaborate....not only would that not make a lick of difference to the spring,but you also have a very good chance of killing yourself.
what you would be doing is turning the spring into a large energy storage device......and if the come along should break or release for any reason,the spring would release all that stored energy in one shot-any part of your body that was in the path of the spring would be promptly removed from the rest of your body......and the spring would be laying on the floor amongst your severed parts with exactly the same amount of arch as it had before.
