Speaking for men, I am not aware of women's pov on this. The agency culture makes you believe that it's fine if you don't have time and energy to focus on your fitness because most of your time and energy is spent on 'work'.
I am not saying that work isn't important. Definitely, it is and you should be dedicated to it, but not by ignoring your fitness. You have to report at 10.30 - 11 am, but your work starts as soon as you wake up and you don't know when your day will end. This makes you tired and you're not left with time to focus on any kind of exercise or activity.
You accept the fact that you're not able to workout because of work. Even if you speak up about this to your management, they won't entertain you. They don't realise how important exercise fitness is for you to function at your best potential. My boss in my previous agency, a PR strategist, always prioritised mental and physical fitness and spoke about it to us. He also told us that your brain goes in a good direction automatically when you feel good and alive in your body, when you look fit, feel fit and feel confident.
I see a lot of men actually putting down others who talk about fitness and encourage good health. This is not about top physic or athlete like body. This is about having some sort of physical exertion as a part of your lifestyle. This will be beneficial for you as well as your employer.
