8. Resistance train
Most people understand, quite accurately, that they need to burn more calories than they take in if they want to lose weight. Unfortunately an understanding of how and when calories are burned is less widespread. The majority of calories you burn throughout the day are not
from physical activity or exercise. In fact, as much as 70% of your daily caloric expenditure comes from your resting metabolic rate, meaning the calories your body burns to sustain life. Muscle is one of the most metabolically active tissues in the body. In other words, sustaining muscle mass requires more calories than bone or fat (and all of the other structures within the body). As a result, one way to ramp up your resting metabolism is to add some muscle
mass through resistance training. Performing resistance training circuits is a terrific way to add muscle mass and burn a ton of calories in the process.
