It seems something comes out every day in favor of weight training over anything else.
Health Test: The importance of being muscular
Sit-up capacity stood out as a significant predictor of mortality in one large observational study. Researchers tested muscular fitness in more than 8,000 Canadian women and men and tracked their survival for 13 years. Those with the lowest sit-up scores were more than twice as likely to die as those able to do the most sit-ups. It's not entirely clear why, according to lead author Peter Katzmarzyk, now a professor at Pennington Biomedical Research Center in Baton Rouge, La. But it may be that sit-up capacity is a good overall indicator of muscular strength and fitness. Many studies suggest that people with greater muscle strength are less likely to develop heart disease, diabetes, and cancer than people with untrained muscles.
