These two women are incredible examples of the benefits of strength training as you age.
And the film says all the right things. Apart from contradicting the stereotypes, they are yet more examples of the (do we dare call it?) fact that working with weights slows or reverses many of the declines of ageing. The extra strength keeps many possibilities alive that might otherwise disappear, and the maintainance or even enhancement of bone density aids the avoidance of injury.
Of course, building your body to the extent that these two do does demand time. But it is not the only way forwards, and two or three 20-30 minutes sessions a week are enough to make a big difference physically. Even so, no one can do it for you, you have to spend the time and make the effort yourself, but the results, equally, are all yours as well.
