Resting skeletal muscle has a basal metabolic rate (resting energy consumption) of 0.63 W/kg [13] making a 160 fold difference between the energy consumption of inactive and active muscles. For short duration muscular exertion, energy expenditure can be far greater: an adult human male when jumping up from a squat can mechanically generate 314 ...

A lunge can refer to any position of the human body where one leg is positioned forward with knee bent and foot flat on the ground while the other leg is positioned behind. [ 1 ] [ 2 ] [ 3 ] It is used by athletes in cross-training for sports, by weight-trainers as a fitness exercise, and by practitioners of yoga as part of an asana regimen.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [1] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
This movement has also been described as negative training. This "negative" movement is necessary to reverse the muscle from its initial trajectory. [1]When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy.

Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy-generating process. [2] " Aerobic" is defined as "relating to, involving, or requiring oxygen", [ 3 ] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [ 4 ]
