The more you sit and the less exercise you do, the less energy do you have to improve. At least make sure that weekends you have hobby that requires to go outside. If you find yourself walking all the weekend is going to be easier to stand at the office. I also have tried playing VR games with "room scaling". It forces you to play standing. The more exercise and time you spend standing, the easier it becomes. But the reverse is also true. If you feel tired all the time, it is hard to start exercising and you need to trick yourself into bootstrapping the habit.
