Years, decades or millenniums after you die; anthropologists from the future world will dig up your bones and remains to find out what kind of people lived during the ancient and barbarous times of the 21st century– and they will say “This guy lifted weights!”
What we are going to discuss today isn’t a training program or a nutritional breakthrough; I just want to leave you with some interesting thought (not that I am going anywhere).
Earlier today I had a chat with my wife. I was telling her that I was very surprised that my arms still looked so muscular although I haven’t lifted weights for a while. I joked that what if ever I decided to become a gay cross-dresser; I would look horrible with all these yucky muscles! Then she told me that these arms will never shrink (too much) because it’s my bones that got bigger.
I was about to tell her that “that doesn’t make sense” when I remembered something that was discussed to us by our anatomy class professor while holding up a dead man’s humerus: “This is the bone where it’s easiest to tell if the person has undergone laborious tasks”.
Has anyone ever told you this:
“You make your muscles big, you lift those weights – so what! You ain’t gonna take your muscles to the grave, when you die, you and me; we’ll be alike!”

And he is obviously jealous of what you have become and is offended by your dedication to your craft because he will NEVER ever muster that same discipline that you have.Follow @AboutLifting

Archeologists and even forensic experts can tell by your bones – OR – your BONES can tell the archeologists and forensic experts whether or not you used to do hard labor or exercised. They can tell more actually – your gender, nutritional state, age, injuries, and even your race:
Many things can leave marks on or in bones. Evidence of disease or injury (trauma) in a skeleton can help identify the deceased. It can also tell us about a person’s general health in life, or the cause of death. Postmortem marks (left on bones after death) can explain events surrounding that person’s death and burial
Activity and Use
Bones change size and shape in response to forces placed on them. Repetitive, heavy use of certain muscles can affect the bones to which they are attached. The bone may thicken, modify in shape, or become roughened where the muscles connect. Similarly, inactivity can cause bone loss, or atrophy — as pictured at left.
Some occupations and habits modify skeletons. The bones of body builders show well-developed ridges where muscles attach. The hips and knees of runners may develop joint deterioration. The right arm bones of someone who is right-handed may be larger than the left.

What’s more interesting is this study that showed how exercise positively affects bone mass of adolescents.
Muscular development and physical activity as major determinants of femoral bone mass acquisition during growth
Objectives: To investigate to what extent bone mass accrual is determined by physical activity and changes in lean, fat, and total body mass during growth.
Methods: Twenty six physically active and 16 age matched control boys were followed up for three years. All subjects were prepubertal at the start of the survey (mean (SEM) age 9.4 (0.3) years). The weekly physical activity of the active boys included compulsory physical education sessions (80–90 minutes a week), three hours a week of extracurricular sports participation, and occasional sports competitions at weekends. The physical activity of the control group was limited to the compulsory physical education curriculum. Bone mineral content (BMC) and areal density (BMD), lean mass, and fat mass were measured by dual energy x ray absorptiometry.
Results: The effect of sports participation on femoral bone mass accrual was remarkable. Femoral BMC and BMD increased twice as much in the active group as in the controls over the three year period (p<0.05). The greatest correlation was found between the increment in femoral bone mass and the increment in lean mass (BMC r = 0.67 and BMD r = 0.69, both p<0.001). Multiple regression analysis revealed enhancement in lean mass as the best predictor of the increment in femoral bone BMC (R = 0.65) and BMD (R = 0.69).
Conclusions: Long term sports participation during early adolescence results in greater accrual of bone mass. Enhancement of lean mass seems to be the best predictor of this bone mass accumulation. However, for a given muscle mass, a greater level of physical activity is associated with greater bone mass and density in peripubertal boys.
So rest assured that a thousand years from now, when advanced anthropologists dig up your grave and examine your bones in their lab – they will say to themselves:
“This was once an asskicker who lifted some BAD-ass weights – this subject used to be an A-LIFTER!”
Music to my soul!
Eat your eggs, A-lifters!
