Any activity that expends more energy than I metabolic equivalent is referred to be physical activity (MET). An energy expenditure of less than 1.5 METS is commonly referred to as sedentary behaviour. Exercise, on the other hand, is a planned, repetitive, and purposeful workout that is a part of PA. More than 1.5 METS are spent as a result of this. Light-intensity activities use less than three METs, moderate-intensity activities use three to six METs, and intense activities use six or more METs. Exercise guidelines are provided by the majority of major professional groups across the world. For most adults, this is 150 minutes of moderate to high-intensity aerobic exercise per week and two days of weight training per week. This programme has benefits for almost every bodily system. Most major non-communicable diseases, such as cardiovascular disease, diabetes mellitus, and cancer, have lower morbidity and mortality rates when people exercise. Furthermore, the healthy lifespan has increased significantly. The benefits of following a suggested fitness regimen are briefly reviewed in this book. There is also a discussion of the possible adverse effects.
