Most people assume bone density is something that quietly declines as you age, and there's not much you can do about it.
That's not quite right.
Your skeleton is living tissue. It responds to the demands you put on it. If you put the right demands on it consistently, it responds by getting denser and stronger.
The problem is most people either don't know what those demands are, or they're doing only one of them.
Here's what the evidence actually points to:
* Resistance training builds bone density... When your muscles pull on your bones underload, your body lays down new bone tissue. Squats, deadlifts, farmer carries - these are the exercises that drive that response. 2 to 3 sessions per week is the threshold most research points to.
** Impact training builds bone density too ... jumping, hopping, and stomping create forces that travel through the skeleton. Your bones adapt to those forces by getting stronger. Even short bouts of impact, done regularly, have been shown to improve hip and spine bone density in older adults. (only do this if it is safe for you personally.)
** Brisk walking maintains it ... walking doesn't build bone density in the way the first two do, but it keeps what you have. It's low risk, sustainable, and worth doing every day regardless.
Most people in their 50s, 60s, 70s and 80s are doing one of them at best. Doing them all together is where the combination becomes powerful πͺπ½π¦΄πͺπ½π¦΄πͺπ½
