4. Wearing a Weighted Vest 

Another way to increase resistance is to wear a weighted vest. This will add some extra weight to your whole body mass. This kind of tip is wonderful for those who focus on building muscles. Besides developing your muscles, you’ll improve your cardiovascular system and tone up your heart. The faster your heart pumps, the more oxygen you’ll need. And if you breathe deeper, it means that more oxygen gets into your bloodstream through the lungs. Oxygen burns fat!
