Strength training (often used interchangeably with “resistance training”) is the process of stressing the body (usually with weights, resistance bands, or the bodyweight) to increase a muscle’s size, strength, and/or endurance ((The influence of frequency, intensity, volume and mode of strength training on whole muscle cross-sectional area in humans. Wernbom, M., Augustsson, J., Thomee, R. Department of Orthopaedics, Sahlgrenska University Hospital, Goteborg, Sweden. Sports Medicine. 2007;37(3):225-64.)).
This kind of exercise triggers beneficial responses in the muscles and bones, as well as the hormonal and nervous systems. Regular strength training, combined with sufficient time to rest between sessions, can also reduce the risk of chronic disease and slow the effects of aging((Resistance training is medicine: effects of strength training on health.
