Ive been slim all my life, always had trouble putting on weight, always the one getting injured in rubgy etc. Basically have you guys got any tips on making and ultra slim, skinny guy into a more toned muscular man!??

My understanding goes in largely the other direction I'm afraid. You're certainly going to have to eat an awful lot for a sustained period of time, and get your gut on your side by only eating clean food so the nutrition is actually absorbed rather the immune system attacking lots of weird artificial crap that was intended as food. To a large extent your basic structure will always be there. Am sure some of the other fitness obsessed guys on here will have some great bulking focused advice.

PS

Eat in a 500 calorie excess. Do compound lifts 4 times a week. Limit cardio. Keep protein 1.5g/lb. Sleep 10 hours per night plus plenty of rest. You likely need to eat more than you think you do or even can.

Don't worry about supplementation or anything advanced yet, just do that for 4 months and evaluate your progress. Modify your calories as your body adapts and as you grow.

That's the basics.

At 18 i was skinny as a rake always had a super fast metabolism.
after taking up weight training i also started eating like the world was coming to an end...
I would go to college with 10 sandwiches all with meat on, i would have 2 pints of semi skimmed milk while at college, along with multiple protein drinks-- i would literally constantly be eating, as soon as i had the slightest room n my stomch i would eat more--anything within reason-- weetabix, omlettes all sorts.-- i worked out i was drinking 10 pints of milk a day
pretty soon went from 10 stone to 14 stone within 3 years.

Im not saying thats what you should do though

like above-- stick to compound movements-- somthing like a 5x5 routine, write down your weights/sets and reps and aim to improve every session.
Eat some nice clean foods, meats, rice, potatos etc, ensure you have some protein with every meal and try and eat about 6 meals a day.
get a good quality protein drink and drop one of them before bed and first thing in the morning along with after you train.

You can get infinitely more complicated than that but thats a good place to slowly build into as a start.

Good advice from folk.

Keeping it simple there are three basic body types, you obviously fall into the hard to put weight on catagory. If you start bulking up, you will find it much harder and far slower, but don't be disheartened keep at it. There are advantage to having a body type like yours you won't have a beer gut later in life.

Boscher was spot on.

It is fairly simple on paper, but you'll need to draw up a proper diet and stick to it. It will take some effort in research and planning your end.

Whilst I would generally agree with Boscher on supplementation, the one thing you might want to consider is a postworkout shake of dextrose and protein.

Also, don't be tempted into the 'eat everything' bulk up diet. It's not neccessary and will just make you fat. I've fallen into this ongoing cycle of bulking up too much then having to diet for ages etc - you don't want the hassle mate.

Peanut butter and seeded bread.

Eat 4 slices of those a day on top of whatever you already normally eat(assuming your weight isn't going in either direction right now), don't scrimp on the peanut butter. You'll put weight on in no time at all for very little cost. Can get peanut butter for 27p a pot in Tesco.

Jay, seriously? Did you get jacked on peanut butter & seeded bread? :0)

A few years back I used to weigh 10st6-11st and I'm 6"6'. I did 20-40 pushups a day in conjunction with already doing football training twice a week for a pub team which was mainly cardio. Was doing a bit of planch progression training.

I put on a couple stone in a few weeks and I've got a perfectly reasonable body right now. I'm by no means suggesting it as a means of getting stacked into some muscly super monster though. I'm reasonably bigger than the average guy and proportionately built with a triangular body shape at 14st. I used to be a skinny Jimmy and that was seriously accentuated by my height.

For someone wanting to break out of their super skinny problem I suggest keeping it as simple as possible, like I did. As soon as things get complicated people start flagging and fall off the wagon into average habits. Get past the major problem then advance onto more complicated stuff later.

lifestyle changes take time, anyone that just tries to switch on full on ninja mode will crash and burn within 2 weeks
