Do warm-up exercises help to reduce weight?
Warm up exercises have to be done *before* a MAIN exercise program or sport . The function of the warm up exercises is to bring your body temperature and heart rate to a level from where you can start the real exercise . and more importantly it helps your muscles prepare for the exercise to be performed .
But if you want to get rid of that extra fat hanging , go for cardio exercises , like running , treadmill running , swimming , step exercises , cycling etc . and when you want to target any specific areas with excess fat deposits . continue with area specific exercise like crunches for tummy , side leg raises for waist (obliques) , biceps curls for arm etc . goodluck :)
