The formal indicator of intensity is how much oxygen is consumed by the body during an exercise; thereby indicating how much fat and energy is burned during the exercise itself.
Any form of activity that relies on moving skeletal muscles. Typing on a computer counts but it will not be enough to lose fat – one would need to raise the intensity.
An exercise in which muscles are free to contract and shorten without changing their tension. Useful because it does not overexert the cardiovascular system, something that its counterpart, isometric exercise, does.
Often shortened to BMR, this essentially indicates the number of calories an individual uses per day with no physical exertion, spent on activities like breathing, digesting, and other base bodily functions.
Types of exercises that rely on intensity so that the oxygen supply from the bloodstream will not be enough, triggering anaerobic respiration. Builds strength, speed, and power, and muscle mass.
Types of exercises that rely on proper oxygen intake and circulation to be able to burn carbohydrates and fats. Aerobic exercises are ideal for losing fat and increasing endurance.
To grasp weights and to lift them against the force of gravity. Gets exponentially more difficult the more mass, and therefore, the more weight the weights have. Used to build muscles.
To get on a bike, stationary or no, and to pedal away. Can offer a clearer advantage to running as biking machines often have other paraphernalia to help with burning fat, like a calorie meter.
