Watch your calories: when you exercise you get more hungry so you have to be careful you are not consuming too many calories.exercise helps loose weight but caloric intake is the most important--chart your calories--use an app lile 'my fitness pal.'

Muscle mass: Since muscle weighs more than fat, some people become discouraged on the scale after they have been diligently exercising. It is more important to focus on how you look and feel than your actual weight. If you are not reaching your fitness goals, it's time to re-evaluate your exercise regimen and your diet. Keep up the good work!
