The answer is yes! Lifting weights for just 30 minutes a week can lower risk of death from all causes. That is an amazing finding!
It has been known for quite a while that strength training can promote longevity, but the "optimal dose" was difficult to determine. Researchers in Japan recently found that weight lifting for 30 to 60 minutes a week can lower risk of death from heart disease, cancer, and diabetes by 10 to 20 percent. If you add aerobic exercise to the mix, you can lower the risk by a phenomenal 40 percent!
Another interesting finding was that increasing the amount of time lifting did not increase the benefits, In other words: short, intense workouts, like the ones we do at CrossFit Koncepts (just under 30 minutes), that combine both weight lifting and cardio, are the perfect combination to help you live longer.
If this doesn't give you a reason to workout than nothing will!
