Believe it or not,
there was a time not too long ago in human history when nearly every person had to lift heavy things on a daily basis in order to survive. Think about it for a minute you will realize it is true. We live in a society where we have made everything as easy on ourselves as humanly possible. Short of each of us having our very own robot at our every beck and call ( which isn’t too far away), we hardly have to lift a finger anymore. If you still don’t believe me just watch and old western or read an old book.
The farther back in time you go the more manual labor our ancestors had to do. Yet the closer you get to our present time in history the more you see problems with obesity, frailty, and heart disease. Fifty years ago, your grandma had a vacuum cleaner that weighed three times as much as your plastic one today. Grandma probably made most of her food from scratch, had a garden and did most of her pruning and weeding by hand, she had some sort of washing machine but she still had to put the clothes out to dry on the line. She did all of this by herself while grandpa was at work in the field, pasture or at the factory. Go back another generation and many people still plowed with teams of horses; forget about tractors or fork lifts to load and carry bales of hay or 100 lb. bags of grain, it was all done with bare human hands and muscle.
While our ancestors were no muscle bound body builders, they were still likely very strong and likely quite lean. Pound for pound they would have given any modern day CrossFit find a run for their money! They were wiry and strong people with true grit. So why else can I say that you NEED to lift? Because modern science says so!
Here are just a few simple formulas for you to think about:
+ Lifting heavy things on a regular basis = increases muscle mass
+ More muscle mass = less body fat %
+ More muscle = faster metabolism
+Faster metabolism = more fat burned or a more efficient calorie burning body
+ An increased load on your bones and joints = more dense bones and stronger connective tissues
I feel like I’ve said this many times before but I can never say enough about the importance of resistance training. When I say this of course I’m not saying everyone needs to be as strong as a power-lifter. I also understand there are some people out there that hate lifting as much as I hate running. But the truth is that all of us need both resistance and cardio training. If my training is lifting focused I still try to get in at least two days of cardio along with my lifting. If you’re a runner, great then run! You still NEED to get at least two days of some sort of resistance training for the reasons stated above. But don’t just take my word for it, the scientific and historical evidence speaks volumes, the truth is you NEED to lift if you want to live a long healthy life!
