As we age, why does weightlifting/resistance training make our bodies stronger/durable compared to laborious jobs that weaken our bodies

Question

Both tend to put stress on our bodies, why does one make us stronger and the other makes it weaker as we get older

In: 16

Answer 1

Some laborious jobs causes long term injuries from having poor form, no proper breaks or warm up.

​

There’s a big difference between:

warming up, during a short set of 10-12 repetitions, taking a 3 min break and then repeating.

VS: Plowing a field by hand, bad form stressing the lower back, no rest time etc.
