I need help!!

[EC3113]

So just a bit about me I’m 16 and not in the greatest shape. I’m not super over weight or anything I just lack a lot of muscle development I guess you could say. I also lack a lot of motivation so that’s why I’m here. I also could use a lot of advice on what works best for getting bigger and stronger muscles so far everything I’ve done doesn’t work.i also have no clue why it says I’m 49 😂
