6'2" 130 is SKINNY!!!
Dude you need to start eating. You probably think you eat a lot but you really don't. I'm 6'6" and I was about 185 a few years ago. I was eating 8-10 meals a day, not snacks but meals. I was getting over 5,000 cals a day while keeping it pretty clean. I got up to 262 in about a year. I'm back down to around 240 now. You can use protein shakes if you are busy or whatever.
Lift hard and eat like a horse and you'll gain some weight.
