Great thread, Ive been lifting for 7years and im only 23. I weigh 95kgs, 5ft10 and only been on the monkey juice once.
I do it mainly to look good, bodybuilding to be more precise. My uncle has won a couple of MR victoria titles and a mr Australasia. His best mate is competing in the upcomming vics, 108kg with a 6pack... Through them both i got a great deal of knowledge in training and diet. Genetics is everything on to how easily u gain/lose and final appearance. People shouldn't worry about it though, 98% of your average gym rats are in the same boat, only a few freaks are just naturally big.
Biggest advice i can give on gaining weight (muscle) is routine and diet. results don't come over night, nor after a month. To think of it logically, gaining 1kg of pure muscle mass per year, train for 10years and that's 10kg of quality muscle. Thats the difference from a mr olympia title, to a dead last place- not even qualified.
Sure for diet, up your carbs and certainly protein. I never did go crazy on carbs, nor did my uncle. looking sloppy, with a beer belly on the off season isnt really attractive, even though u can still lift the world. People underestimate the importance of diet, diet is the key. I never counted calories/carbs or protein, I just know how much to take. Only supplements you need naturally are a protein powder, bcaa's and some good fish oils if you don't get it from diet. The supplement industry is almost as big of a scam as the church is. don't be fooled with the crap they release with all the false hopes. Alot of its a sugar hit/ and or mind over matter. Ones that ive heard of that work 'ok' are jack3d and whiteflood. You think ronnie coleman actually took jack3d to gain all the muscle he did? yeah right.
I could rant on for hours of training routines, but my biggest advice id share... 6packs come with diet, for all you pretty boys. also, never do an 'arm' day. the best bicep building exercises arent as obvious as u may think
. All the best with whatever your goals are dudes.
