Light weights just as good for muscle building

Lifting less weight more times is just as good at building muscle as doing it with heavy weights, says a new finding.

`We found that loads that were quite heavy and comparatively light were equally effective at inducing muscle growth and promoting strength,` says Cam Mitchell, the study`s co-author and a doctoral candidate in kinesiology at McMaster`s University in Ontario, Canada.

The research suggests that the key to muscle gain is working to the point of fatigue and challenges the widely held belief that training with heavy weights is best for muscle growth, the Journal of Applied Physiology reports.

How to go from stick to thick

`Many older adults can have joint problems which would prevent them training with heavy loads,` says Mitchell. `This study shows that they have the option of training with lighter and less intimidating loads and can still receive the benefits.`
