Go to the gym three days a week. Alternate between two workouts:
barbell back squat 4x8
bench Press 4x8
dumbbell row 4x8
barbell military press 4x8
chin up (attach weight if it gets easy) 4x8
Add weight whenever the 4x8 become easy. Ideally, this means ‘every workout’ for quite some time. Don’T start with weights that feel fucking heavy, learn perfect technique. Hint: perfect technique means you make the weight look easy.
Eat 2,500-3,000 calories a day. CLEAN food, no sugar, not too much junk food. Get 150-ish grams of protein each day. Try to get them from actual food (meat, fish, eggs, dairy, legumes), use protein powders sparingly.
Do NOT think you can just eat and be big. Your diet is the fuel but you won’t go anywhere if you keep missing training sessions.
Also, if you’re 160 at some point in the near future - pat yourself on the back and realise it will take a while to get to 190.
Lastly: You can find all of this in the stickies on top of the beginner forum. Do work, don’t expect strangers to spoon feed you all the information you need.
