big biceps

get a powerball, i got one for £40 from play.com and it has increased the size a fair bit..i am 14 and lift weights occasionaly but a powerball is easier and more efficient!
worth £40 also do press ups they help alot i usually go and do 25 7kg dumbells in the morn (25each arm) get in from school try and get on my bike and do a good few miles,then 25 press ups, usually go out with mates for a few hours get have a go on powerball for 15mins ..
i only do it for downhill,cross country running and when i have a race on my motocrosser 8) and it has helped alot

i see what you meen big n daft, i do not do it just to have bigger biceps i mainly do for when i am racing (motocross), its not easy to keep the front end of a 125cc motocrosser down when it kicks in to its powerband ..that is why i started as i used to really tire my arms out when racing and end up with cramps in my forearm.. not good in the middle of a race, a powerball has helped alot with that and doing a few weights etc.. does make a difference in motocross and downhill

A powerball is a good thing for you then Jack, because it exercises the forearm muscles, which is where your getting the pain, although I'd guess and say the size of the muscles won't make a jot of difference, it's more likely to be a 'stuck in one position cramp' type of problem. It could also be pressure on the ulnar nerve, this runs into the base of your hand, on the opposite side to your thumb, so on your right hand it will be on the left hand side as you look at your palm. This is a well known cause of pain in cyclists, but any pressure for any length of time on it will cause pain and numbness into the forearm. S'why cycling gloves tend to have gel pads on certain parts of the palm.

You'd probably see more benefit from changing your grip every few minutes or so, especially on your throttle hand, because I'll bet it's your right wrist/top of right forearm that hurts more than anything what with it being bent backwards to open the throttle. Do the movement off the bike and you'll see exactly which muscles are working to do it.

Could also be you need to get your bodyweight a bit more forward rather than trying to hold the front end down with your arms. As soon as you clench muscles, they become liable to cramp, try it with the big muscles in your thighs, after 30 seconds or so, they'll hurt....a lot.

I don't mean to sound like your mum, but honestly any free weight use at yours and KSO 's age will really do more harm than good. Lifting weight is not just about how much weight you can lift, to get any benefit and to prevent serious injury, proper form and control of the weight on both the contraction and extension stage of the lift is vitally important. Training to destruction (which is pretty much the only way you will see serious gains) is a seriously dangerous activity without proper supervision or at least someone around who can get that weight off you in an emergency.

In basic terms, the muscles take the bulk of the weight, but tendons, ligaments and your skeleton share the load, all of which are still quite elastic or soft at your age. Your going to do it no matter what anyone says but please get someone to show you the proper way to do it at least.

maybe you just need to choke the chicken more.
At your age I had a right bicep bigger than my thigh !!

My right bicep is begger than my left bicep.
but i'm working on it. :P

I genuinely do have pretty prominent muscles on my arms, and immensely veiny arms, streching from the backs of my hands, up to my neck etc. I was once questioned by my head of house at school if i was on steroids, due to a f*cked up stupid rumour going round and reaching her ears :x

people at my school ask if i work out loads etc, but i never have in my life, apart from maybe once in a blue moon at the school gym etc. it's all from riding, and the other sports i used to do wheni was a bit younger, prior to my knee injuries. i put some of it down to half a year of xc riding on a dh bike as well!
I've just turned 16, and would like bigger pecs, but hey, he who wants doesn't get. Stop being a posing arse, and your muscles will develop if you put the effort in. I scorn people my age who go on about their muscles, and how often they work out, it's just a bit pathetic. have fun riding your bike, and if you ride enough your body will catch up mate.

Definitely wait, you are almost certainly too young to be trying to build up muscle bulk, you'll most likely just injure yourself or cause growth problems, particularly if you train without proper supervision. If you want to improve your general strength, particularly in your core, which is useful for everything, get a yoga ball. they are about a fiver from argos and if you use it like a chair for most things, like working, watching tv etc then you'll find your core stability will improve in leaps and bounds.

i asked my p.e teacher about it and he said it will help in alot of sports and it was him who suggested it to me after i broke my wrist ina few places he said " start of with light weights while its still weak and work youur way up the bigger ones to get more strength back in your wrist"

I have to agree with the majority of people on here at 14 it's pointless and will do more harm then good.
I was pretty much just skinny my whole school life but growing up muscles/strength comes naturally with sports/activities. I'm 19 now I don't have the "poser" muscle look at all but do have big forearms and alot of upper body strength. I never trained as such I just work as a bricklayer and rock climb 1-3 times a week, I only do it every other day at most so I have rest time. I'm very new to biking as I want to get a bit more strength in my legs and stamina etc as well as loving being outside!

I just find that if you are doing something you enjoy biking etc your body will adapt and you get the gains in the places you need them. I don't see the point of doing anything for an image if I don't get useable gains from it.

Ben you should learn to do it with you left, you are a crime against symmetry
