Dumbbells

Thanks for the suggestions people. Some were a lot stranger than others

But yeah I guess I'll go for the screew option ones as it makes a lot more sense

You can easily do body weight moves which will help, press ups and dips

you could also start fights with big people, girls love fighting

If you can, get a bench and a pull up bar as well. Work all your muscle groups.

I'll start with the dumbbells for now and then move from their. I'll be as big as Steve Austin come December

Diet is arguably more important. If you lift weights without eating enough protein, your muscles will canibalise themselves. As BritPlayers said, don't just focus on your arms, you have to work out your whole body and fuel it properly. Forget about short term goals and try to see it as a lifestyle improvement.

ObjectiveFan is correct; diet is essential.

If you're 11 stone, for example, consuming 2000 calories a day, then irrespective of how much weight you lift, you're not going to grow beyond 11 stone without consuming more.

Of course, some fat may be replaced by muscle, but there's only so much muscle you can grow on a regular diet.

The best thing to do is to count how many calories you eat a day on average, and try to add 500 to this amount. This should help you gain a decent amount (half a stone, as a rough guess).
When you start to plateau, simply add another 500 calories.

Not sure how much weight you have, but for hypertrophy (build muscle), it's best to lift within an 8-12 rep range for 3 sets, with around 1-2 minutes rest in between sets.

Separate your workouts into different bodyparts as well, so as to allow them to rest and grow - remember, muscle development is about damaging the muscle fibres and allowing them to grow back stronger; without proper rest, you'll be overtraining, and all of your hard-work will be for nothing.

Not sure how many days you have available to work out, but generally people start with a 3 day split, something like:
Back and biceps (since moves like chin-ups and underhand rows hit both muscle groups) on Monday; Legs and abs (not complementary, but I always liked to throw abs in with legs since there was only so much you can do on legs) Wednesday; and Chest, Triceps and Shoulders (all pushing movements that tend to work together in exercises like bench press, overhead press, etc).

That's just a rough layout for a workout; you can do it however you see fit, so long as you're working out enough to encourage growth (3 times a week is good for most people, but I even went with 6 with excellent results), whilstm allowing each muscle group at least 2 days rest to fully recover, before hitting them again.

For back and biceps, chin-ups are probably the best exercise. If it starts to get easy (you can do more than 12 at a time), try and do some with some weight in between your leg. As with all muscle groups, you need to keep trying to improve the weight and/or number of repetitions you do - otherwise there will be no need for your muscles to grow.
In addition to chin-ups, you can do hammer and bicep curls for the biceps, and bent over rows (type into youtube for demonstration )for back.

For legs, if you don't have a squat rack, you can try lunges with weights (again, it's probably best to go on Youtube - when you're doing it with weights, good form is important) and if you have enough weights, deadlifts and excellent.
Working out the legs is excellent for sport; since I started doing deadlifts, I've become so much quicker!

For abs, make sure you do your crunches and leg lifts with weight when you can. Again, abs will only grow if you increase the weight they have to lift

With regards to chest, you can do dumbbell or barbell press (if you don't have a bench, you can do them on the floor, providing you have space - I balance my dumbbells on a stack of books, lie down next to the books, and take them off so that they're already in position) or dumbbell flyes.
For triceps, dips (which is also good for chest) are great, but it might be awkward without the right equipment - I do mine between chairs, but I'm not sure my parents would be overly pleased if they found out) and overhead tricep extension.
For shoulders, try lateral raises, overhead/shoulder presses, and Arnold Press.

This is a pretty brief run down, but should give you a good starting point.

Bodybuilding is a slow process, but honestly, in a couple of years, you will look back and realise just how far you've come.
I was in your position a couple of years ago, but 3 stone of muscle later, and I'm more confident than ever!

If you have any questions, just let me know, and if you happen to see me on another thread in future, I'm more than happy to give you some further info, if required :D

if you specifically want big arms, then buy said dumbbells and look up on the internet different 'arm' exercises one can do. make sure you include tricep and bicep excercises - there will be a range of things you can do with just two dumbbells.

i would advise you to do lots of press ups, as they work your chest, arms and shoulders. you can do a few shoulder excercises with dumbbells as well.

Wow DaStuDogg this page is definitely getting bookmarked

I'm a student so yeah I'm almost always skint so some of the things you've mentioned will set me back touch . I'm planning on doing pressups, sit-ups, dumbbells and a big of running for now. Need to work of that Christmas fat. I play indoor football once a week which for me turns into a proper work put lol. I'm such a noob.
Are you a personal trainer by any chance? Impressive stuff

No problem And I'm not a trainer; I'm a student who, like you, decided they wanted to get bigger, and it's pretty much become an obsession since!

Press-ups and sit-ups are good, but you need to try and lift as much weight as possible. Once you get comfortable doing regular press-ups, start aiming to make it more difficult for yourself - perhaps by lifting your feet off of the ground or doing some harder variations (clapping, one-hand, or some of the more obscure ones you can find by searching the web).
With sit-ups, as I say, try and incorporate some weight.
I spent my whole life trying to get a six pack, but despite being skinny and doing 100 crunches a day, it never came through. About a month after I started doing heavy weight sit-ups, my abs became visible! Of course, you have to have a reasonably low body fat, but if you're going to start doing running, as you say, then your bodyfat % should decrease.
If you're looking to burn fat, it might be worth looking up 'Interval Training' which is supposed to be a lot more effective than regular cardio. I personally do some Plyometrics with little rest in-between; this helps to burn fat and improves speed for football
Also, if you drink tea or coffee, it might be worth replacing it with green tea, as this helps to boost metabolism (as well as improve cognitive performance and general health).

If you do have a chin-up bar, or perhaps a sturdy door you can hold onto (again, be careful with this), then pull-ups are the best exercise for building mass in the back (makes you look a lot broader) and are good for biceps.

As firingblanks says, you can usually find good advice for exercises by searching Google, so if you are struggling to work out a certain bodypart, it's best to look it up - I could never find a good dummbell exercise to work my back, so instead of looking one up, I neglected it, and now my back is lagging behind a bit.

Anyway, best of luck, buddy! I really hope it goes well for you
