Regarding us guys who live in colder climates I have a question. We all know that our nuts retract when it's cold out or when we are being physically active. If you put on weights prior to going out in the cold, and at the same time you physically extend yourself (running, climbing, exercising, etc.), your cremaster cord is going to try like hell to pull your nuts in closer to your body, but won't be able to because of the weights. This to me is a classic isometric exercise, with your cord pulling up against a weight pushing down. Here's my question, might we be making our cremaster cord stronger in this situation? If we are making it stronger, will that make it harder to stretch it in the future? Or will the cord become fatigued and quit resisting, making it easier to stretch in the long run?
