what sort of exercise would help me to lose the fat from underneath my arm pit it causes me to sweat and its a bit embarrassing i only sweat when im in the hot sun as i live in the Caribbean region. i've also realized that certain deodorants dont agree with me so i've switch back to my original deodorant and so far it has kept me dry but as soon as i hit the hot sun i start sweating. ive never had this problem until now tht i've gained a lil fat under the arm pit i would really appreciate ur timely response. the deodorant that i use is Lady speed stick (invisible dry powder fresh, 24H Protection)
