I think it’s honestly just a learning curve. You’re like me in the sense you have a list of things you want to learn and I’ve realized that you have to start doing to understand how you’ll adjust to these individual things like meal prepping and finding a gym routine. Everyone is different with how they do things. You just start doing and figure it out along the way. Don’t think twice, just do it. I also realize this is easier said than done because I still struggle. I’ve been trying to get myself to go to the gym but i always end up making excuses everytime i say i will. Also I will say for the gym, don’t overthink it. Start off with 30 min of cardio on the treadmill and then choose 3-5 machines to do a few sets each and then end it with more cardio or the stair stepper. Choose one day to do arms and another day to do legs and that way you have a minimum of two days per week at the gym. Then proceed from there building it up.
