Odor build-up comes from when you do a workout or do heavy activities that require you to sweat. The odor comes from bacteria that are present on your skin. The stink happens when sweat meets bacteria. Bacteria break down the long-chain fatty acids and hormones and sulfur compounds, resulting in odoriferous molecules.
