If you're talking about long term working out, motivation will not cut it. It has to be determination/making it a habit. Like - "Time to take a shower", "time to workout".

But working out doesn't mean you have to push yourself till you feel like puking. Start small, do 10 squats at lunch and another 10 when you finish your work day for e.g.. Do something you find fun, not something that's just "well running is exercise so I guess I have to do that"

Hey, sorry for the late reply, i have found that whenever i set a goal of losing x amount of weight, i always slowly lose motivation. So, this time i have set myself free from any restraint, and am focusing only on the good benefits that excercising gives me (mental clarity, less anxiety also slow and steady weight loss). There is no constraint to do x amount of workout everyday, instead its just get out of the house, get walking, get some sun and if you want to, then lift some weight. And surprisingly, i haven't missed a day.
