High-Intensity Interval Training is the way to go. March 5th 2017
Many people still believe that spending an hour every day on a cardio machine is the best way to lose weight. Empirical research has proven that steady-state cardio (such as walking, or even running, on a treadmill) has benefits that decline once your body adapts to the exercise over time.
A more effective and reliable way to elevate your metabolism to burn fat is to do high-intensity interval training (HIIT) and resistance training. HIIT involves a rotating of a high-intensity phase with a recovery phase; for example, running fast for a minute and then jogging or walking for a minute. Resistance training increases the mitochondria in muscle cells, which are the “powerhouses” in the cells responsible for metabolism. The more mitochondria in your muscles, the more efficient your body is at burning fat.
Do not overdo it with weight or with too many repetitions; as a general guideline, you should feel moderately sore for about two days after lifting. (If you are unsure of how much weight you should lift and how many repetitions you should do, consider hiring a certified personal trainer to guide you and to protect you from injury.)
