Various time frames can offer advantages and disadvantages.
It’s not unusual for a new gym goer to try to figure out the best time to work out. Many factors can come into play, and various time frames can offer advantages and disadvantages. At the gym I go to, we have a dedicated group of people who work out in the early mornings. Many of these people have work and family obligations. They don’t want to give up family time to go to the gym after work, so they get up early to fit it in.
That free time after work can be a strong advantage. This group doesn’t tend to hang out and socialize after the work out. Some gym goers might miss that aspect. For people who are night owls, working out in the early morning may seem impossible.
