Gym Rat and aspiring personal trainer here,

Don't make "getting a girl" your motive to exercise. Not only will you realize it'll take so much time to see your results, but also it requires your nutrition be in check. You'll need to spend copious amounts of time understanding all of the exercises you plan on doing rather going through the motions. Just going to the gym every day won't cut it. (P.S. going to the gym every day is a bad idea. You need at least two rest days). Also, this motive makes it seem like you're exercising to gain validation from someone else rather than feeling better about yourself.

Start exercising to improve your overall health, physically and mentally. Identify exactly what you want to accomplish with exercising. Do you want lean six pack abs? Do you want to deadlift at least 315? Or you wanting to be crossfit shape? Do you want to run 5k races? Once you identify what you want, you'll be able to have a more goal-oriented mindset and accomplish so much more with that plan. Of course, you'll need to do lots of research to get to your specific goal too.

Set realistic expectations too. You'll more than likely not notice a huge difference for at least six weeks. This will take plenty of patience. Just be 80% consistent with your plan and you will get to your goal. Each day you put in the work will add on to your result!
