“Metabolism” is the name of the bodily system that converts food calories to energy needed to perform various tasks, like pumping oxygen to muscles during a long walk. Many variables contribute to your metabolism, including heredity, gender, and age. But you can quicken yours; here’s how.
During weight training, muscle tissue is stressed; afterward, it’s repaired―which raises metabolism. A woman who strength trains three times a week for six months can build enough muscle to burn 10 to 32 extra calories a day, according to Robert Wolfe, PhD, professor of geriatrics at the University of Arkansas.
