Anecdotally speaking, the folks who include muscle-building exercise in their lifestyle – from bodybuilding to strength to simply progressive-gain weight lifting – will all claim to live longer, stay younger and feel happier. But we live in a day and age that is crazed fore scientific backing; endless, repetitive accounts are somehow deemed invaluable to the average first-world perspective. Unless there's schnazzy studies backing a claim, very one presumes it's hogwash. And so those accounts of long life from those us who lift big and get beefy – regardless of spanning at least 5,000 years of repetition – are disregarded.
Fortunately, Science is gradually catching up to the simple reality that the most consistent accounts from humanity are, indeed, often believable. More and more studies are being applied to what us musclebound folks already "knew" and proving that – surprise, surprise! – our claims for longer life are actually dead on the mark.
Recently we Snooped a study posted by Scientific American that showed a strong correlation between muscle gain and longer (and presumably thus healthier) lives. The traditional dominant form of assessing human health based on body composition factors – the classic "BMI," or body mass index – didn't really indicate longevity benefits. You could had what doctors consensus is a "healthy BMI," yet this factor actually shows little correlation to long, healthy life.
However, higher muscle mass showed a remarkably strong correlation with longevity. You're reading correctly: a study of 3,600 seniors hints that those who built muscle over the long run may live a longer run. We have to say "may" live longer, because all the study showed was correlation. Correlation between two factors does not show causation between them; just because the more muscle-developed lived longer does not mean their muscle-building was the cause.
However, we at the Snoop have to hearken back to the consensus of the Humanities on this one, and presume the correlation is not merely a nifty coincidence. Perhaps the repetitive claims over the millennia that bigger muscle mans longer life are not just hype.
The study that suggests more muscle may lead to longer (and presumably healthier) lives compels, for us at The Next Level, a pro-bodybuilding argument which contrasts the religious use of exclusively CrossFit as one's primary mode of exercise. You see, muscle-building slows up unless you intentionally try to continue the process. While the dynamic/functional exercise movement (i.e., CrossFit) will certainly put some muscle on a person, there is a limit due to the sheer repetitiveness of the pursuit. In other words, to get the real benefit of CrossFit, one must simultaneously also seek to at least push the agenda of muscle gain as well. Just repetitive CrossFit alone is no better than just bodybuilding alone.
