We all suffer the same time issues. I could give you a great deal of fitness advice on that, but, allow me to give you some business advice.
I too run a business, part of which is fitness, production related so hours are crazy, and the business is International. I can literally work 24/7 if I let myself.
It is great to own your own business, and even better when you know how to take some time for yourself.
Remember to run your business, don't let it run you. I had a very good friend of mine that had a hugely successful restaurant, his body was impeccable and his diet even better.
You should see your advantages, you have access to food and cooking equipment so keep your own stock and be sure to keep your diet clean. But, what my buddy (Pete) did was take a change of clothes and slip out between the lunch and dinner crowd for 90 minutes.
Start you employees and your management/staff off on the right foot and let them know that your gym time is your time...PERIOD. If you cannot trust a manager or trusted hostess/employee for 90 minutes, look for new help.
Get in the routine, when you look your best and feel your best dealing with the public is so much easier.
Just remember, Run the business, but, don't let it run you! Time management, focus, and some adjustments...
Thanks it man.
