– Intensities of physical exercise.

Physical exercise intensity	VO2max*	MET&
Very light	<37%	<2
Light	37–45%	2–2.9
Moderate	46–63%	3–5.9
Vigorous	64–90%	6–8.7
Near-maximal to maximal	≥ 91%	≥ 8.8

MET: Metabolic equivalent of task (index of energy expenditure; 1 MET = 3.5 mL/kg/min oxygen uptake). *VO2max: Combined capacities of the pulmonary and cardiovascular systems to deliver oxygen to contracting skeletal muscles, and the ability of those ^&muscles to utilize it.
