Start slowwww and work up to it. Check your weight for your height and age. If it’s grossly wrong then you need to diet, do aerobic with anaerobic. That’s work heart and muscles. Get a liter water bottle and keep it with you. Sip throughout day and empty at least once a day. Cut chips, fried foods, and sugar out. If you can’t then cut it in half. Ok:
What is your body type? Do you know the types? No? There are 3, with people moving to one or regressing to another at any point in their lives so there are actually 6, they are based upon ectomorphic (lean hardgainer) mesomoph (responds to training) and endomorph (eat a Twinkie it becomes a Twinkie, on your ass) first things first. You have to keep your body in a thermic state, that is a burning calories state. Count your meals per day. Whatever it is, double that ie if it’s 3 make 6 nutritional ones. Not that slop you been eating. Once you begin training, you should train with intensity and duration hitting your target heart rate or max at least three times for 45 min to an hour, no more than an hour and a half.
If you walking in the gym yapping and chilling you ain’t doing sheeeit! Get off your fukking fat ass and grab some real estate on the floor you maggot! If you see spots , dots before your eyes you are doing too much too quick! Ease off!
Start here with your core.
Assume the plank position with elbows on ground like in video. If you can’t hold it for a minute and are trembling like a leaf in a cyclone then you are a sheep waiting to be killed by the wolf and your core is powerful weak.
To really accelerate your core get a 15lb to 20lb weight. Stand in mirror and rotate it up, down and side to side in a slow, deliberate circular motion. Do 4 sets of 10 reps. Your arms may feel like jello after but if that is too much do 10 lbs until you can do it. Then go up. Keep going and start doing it with your legs raised on floor like in video except you also use the weight. Go slow! Don’t jerk. Golden rule is if you start trembling, have poor form then back off. Do this for 90 days.
Assess progress and setbacks. Re attack it! Summer is coming up ! You fukking welcome son!
