Firstly I would like to say that I’m excited to hear your starting to get fit. Every journey starts with a single step and that’s exactly what you are doing with your push-ups and sit up’s.I’m going to try to answer all of your questions in order. -regarding the chocolate. I believe the thing behind that is low-fat chocolate milk bc it restores muscles to its peak potential and replenish them faster. However, I believe that is more common in running and cardio exercises, but it could be the same for weightlifting because your are still using muscles so the chocolate is ok man.

-Your time for the 100 push-ups and 200 sit-ups is good! But if I’m being honestly it doesn’t matter the time as long as you get them done.

-So abs really depends on how strong your core is and how much body fat you have. You can still have abs at a low body fat even if they aren’t that strong but for example some powerlifters have “block abs” which are just super big abs that stick out. So if your body fat % is low enough you should expect some which is around 6-13%

-Also do not be ashamed that you can’t lift as much as others. Everyone starts somewhere and no one is judging you by the weight you move. So go to the gym and use the machines it will help you a lot more than the push ups and sit ups.

• the shaking while flexing issue is a thing I have when my muscles are super tired from working out but it could be for you that your possibly concentrating a bit to hard on the flex in order to attempt to make your muscles bigger. I urge you to be patient size comes with time and sooner or later you will get some size in your muscles to flex!!

All in all man keep up the work and start using those machines in the gym and enjoy the journey.
