The notion that lifting heavy weights will make you big and bulky may be a myth, according to a New York Times article.
In order to get bulky muscles, most people would need to consume extra calories as well, to the tune of well over the 2,000 daily amount recommended for many adults.
“For people who lift weights to tone up and slim down, experts say, a regimen that includes a combination of challenging weights and fewer repetitions can help significantly. In a 2002 study, for example… subjects lifting more weight fewer times burned more energy and had a greater metabolic boost after exercise.”
The conclusion? Heavier weights and fewer reps may be your best route to improving your muscle tone.
