Just read through all of these comments. Some I agree some I do not but hey I’m no expert. I would night suggest a book I just finished reading(I hate reading). The book is named “bigger, leaner, stronger” it’s not just another stupid exercise book it actually gets into the mental game. Plus helps you learn about nutrition (which I’ve tried to read about before and never understood it until now), different diets, training programs(bulking and cutting). The biggest part for me was the mental game which I could carry over to my shooting. I’ve only been doing what the book says and I am noticing larger differences than I ever have. I’m 31 and was fairly in shape before always active running 5k races and stuff still. At one point around 20 I was heavily training in MMA. Right now I “feel” like I’m in better shape than I was then. My cardio isn’t what it was then but it’s getting there. You CAN do this. Keep us updated. Get a Fitbit to count steps and join challenges heck let me know if you get one and I’ll link up with you.
