Lifting weights with good form while using a well constructed and periodised training programme, can not only make you stronger, but it can also improve structural alignment, provide support for joints (both cartilage and soft tissue), both of which reduces ware and injury risk. So when we do our running we remain injury free.
* Why Strength Training? *
Strength is the most basic requirement of all human movement, so it should be your primary goal.
With increased strength all things become easier. Aging is slowed and even reversed.
“Stronger people are harder to kill, and generally more useful to have around” Mark Rippetoe.
