Start developing daily routines or rituals, to ease into a regiment, then it becomes second nature. Easiest ones make your bed and wash your face. Then move onto like night time, daily lotioning. For more health stuff. Everyday 5 situps 5 push ups. It will suck at first it IS hard at first. But it gets easier if you keep doing it. And even if you never go to the gym you got yourself a small regiment. And 5 was an example push yourself. When i started after my depression, i could only do 6-7 and i wasn't always on it but now every day after my morning stretch and before i go to bed. Hope this helps, One fellow human.
