You can get away with it in your late teens and early 20s but once you hit your late 20s and early 30s you will start noticing your body is ageing and ageing quick.
Strength training helps to delay your body ageing by increasing your muscle mass. We know that as we age, our muscle mass depletes, which leaves us susceptible to all sorts of potential injuries or risk to diseases.
Lifting weights can keep injuries at bay and help you live a healthier lifestyle. For men, especially for testosterone stimulation.
A higher metabolism, more balanced body fat, ability to carry out functional daily movements injury free, reduced stress levels, the list goes on.
It may not be the cure for ageing, but it certainly helps.
