If you want to lose weight, you need to maintain a calorie deficit, which means that you need to burn more calories than you consume. That's an overly simplistic way of looking at weight loss, though; picking the right foods, increasing your water intake and getting adequate sleep can all play a role in weight loss, too.
Strength training exercises can also help with weight loss. That's because this style of workout can help you build muscle—and the more muscle mass you have, the more calories you burn, even when you're resting.
