Does pitching when it is cold out hurt your arm more than a regular day?
I don’t know by facts, but my arm feels like it can throw forever when it is hot outside (like 25+ degrees celsius)
Your right Lizard it is easier to get warmed up.
For the original question it would depend on specific temperature but the lower you go the better you should be warming up. If its 85-95 out your body is already warm to start strething but if its 40 out your muscles are tense and cold.
