Same problem here with the sweat bro. usually its the cloth you wear that makes it smell. wash them with those antibacteria and dry them under sunlight.

most of the time you sweat because your muscle are tensed. whenever youre out, try to relax, deep breathe, and notice which part of your body is tensed. dont clenched your butt/fist or suck in your stomach. even sitting or standing straight for a long time would cause me to sweat alot.
