I'm male 24. I'm occupied with my office work so I'm trying to minimize the effort in exercise as best as I could. This means that I don't go to the gym, and I don't buy any equipment. The only thing I can do is making it as a habit in a daily basis, and make it harder everyday. In my "definition", a simple plan is a plan that I don't need to remember or look up at all. My current plan follows this formula: "yesterday I did x in exercise 1, y in exercise 2, so today I'm going to do x+1 and y+1". After every 20 days, I add a new exercise, so ultimately I will do every exercise. I only do the workout on a specific time in a day (around 6 pm). I don't have any set, just focus to finish one exercise, then take a rest, then move on to another one.
Since I know this plan is to way simple, so I have set my mind that it can take year(s) for me to see the result, and time frame is not my worry. I haven't changed my diet, because I think it's starting to be complex, and more over I don't eat much fat or fried food. I have been doing this for about two months, and I can see how my body changes via the mirror.
Q: However, when looking down I barely see any different. If I stick to this plan, can my muscle be sharper in the future? Or do I have to take care with my diet, or follow a good program?
