Know Your Diet
No matter how hard you exercise, it's true: it can be hard to lose weight if you're not changing your diet. "You can't exercise enough to overcome a poor diet," says reader Brittany. "The diet part has to come first." If your weight isn't budging, regardless of how much you're working out, take a look at your current eating habits to see if you are eating the right amount of calories for your body and your goals.
