Strength training has been proven to increase bone density, increase lean muscle mass, improve posture, and reduce the risk of injury.

Bone density contributes to the strength of the bones; and their density changes in response to body weight and to weight-bearing exercise.

骨密度代表骨的强度，骨密度依随体重和负重锻炼而相应升降变化。

The control group showed a decrease in soleus muscle mass and strength, the development of insulin resistance, and a loss of bone mineral density and resistance to breakage.

The study is said to be the first to examine in detail measurements of bone strength instead of bone density.

The study found this loss of bone strength increases the risk of broken bones later in life.

Not only does the robot look Terminator-esque, but it's been designed to mimic the muscle system of a human (with bone-crushing strength, of course) and will be programmed with a semi-autonomous AI so that the android can learn new tasks, all of which is just a little too much like the Terminator for our comfort.

Research has clearly shown that strength training can help to reduce the pace of bone loss, while some studies have demonstrated that such training can actually help to build bone.

The combination of positive stress on bone from aerobic and strength training leads to stronger, denser and more functional bone.
