Weight Loss and Toning

Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue.

Toning exercises are physical exercises that are used with the aim of developing a physique with a large emphasis on musculature. In this context, the term toned implies leanness in the body (low levels of body fat), noticeable muscle definition and shape, but not significant muscle size (“bulk”).

Research and basic anatomical knowledge imply that the notion of specific exercises to improve tone is unfounded. Exercises can aid fat loss or stimulate muscle hypertrophy, but cannot otherwise improve tone.[1] The size of the muscle can change, as can the amount of fat covering the muscle, but the ‘shape’ cannot.

The word tone or toning can be misleading as it suggests that spot reduction is possible where localized fat can be reduced, which it cannot. It is suggested to use the words muscle building or fat loss instead.
