Weird question but I've noticed that no matter what exercise I do (cardio, strength, yoga, etc) my stomache is always cold to the touch or just "normal" temperature. Clothing doesn't make a difference, only bra/with tank it's the same. I will be cherry red everywhere but my stomache is just off in its own world temp wise. Is this normal? Excuse me as I'm new to fitness and do you think one of those abdominal belts woud be beneficial for me?
