What is when a guy starts working out?

As an AI language model, I don't have personal experiences; however, some general information is mentioned below about when a guy starts working out:

The best time for a guy to start working out depends on their overall health and fitness. In general, once they reach puberty and have grown into their bodies, it is often a good time to start focusing on physical fitness. This is typically around the age of 13 to 15, although some may start earlier or later.

It is important to start with a plan and to gradually increase the intensity and duration of the workout to avoid injury or burnout. Many guys start by doing bodyweight exercises at home or joining a gym to work with a personal trainer.

Regular exercise has numerous benefits, including improving strength and endurance, reducing the risk of chronic diseases, and improving mental health and wellbeing. It is never too late to start working out, but the earlier one starts, the greater the long-term benefits.
