The dark part around the bone is muscle. The white part is fat.
What you'll see in this picture is that the 40 year old and 70 year old have the same amount of muscle on their bodies while the 74 sedentary man does not (obviously).
Studies show that an 80 year old who lifts weights is stronger than a 30 year old man who doesn't.
What you should take from both of these examples is that you either use it or you lose it.
Working out can be the difference between living a quality life until you're elderly or living in a nursing home needing someone to wipe your butt for you.
I'm always keeping an eye on the future with my actions in the present. This goes for my body and business.
What about you? Do you choose to use it or choose to lose it?
It's always a choice in the end.
Make the right one.
