Conquering The Jiggle With Weight Lifting

You don’t need to lift heavy weights to firm up what jiggles, because repetition is just as effective at building muscle, according to researchers at McMaster University in Hamilton, Ontario, Canada.

As long as you exercise to the point of fatigue, you can choose to use heavy or light loads and get similar results, say the researchers. They tested young male volunteers who either lifted heavy weights for fewer repetitions or lighter weights for at least twice as many repetitions. Although the heavier weight group developed a bit more strength, the gain in muscle volume was the same, according to the research in the Journal of Applied Physiology.
