I'm 14 I have been told i am skinnny but I'm about average. I'm 53kg(117lb) and I'm 5'8. I got hardly any muscle in my arms I can do twenty pushups in a row. I can do 100 situps but I need some sort of program or arrangement other wise i have no motivation to work out. I'm a big eater and I'm always hungry I love all foods so eating proteen isn't a problem. I got waits at my house (2kg) but apart from that my work out can be done at home or out side. I play during the recess with my friends basketball.
could someone give me an idea of where to start and how much to do... if I start something I tend to finish it so I don't think I'll give up and I'm ready to work hard to achieve my goal.
Thanks,
Dylan.

I'm a little older than you, but I had the same problem until about two weeks ago. I'm a college athlete and after I had a rough freshman season, I knew I needed to start getting into shape but I didn't have a good workout routine. My aunt who does ironwoman competitions and has trained with Carmichael, Lance Armstrong's trainer, told me about NextFit. With NextFit you literally get to choose from thousands of personalized workouts, while having one of the world's best trainers in your ear anytime and anywhere...Since I started using it I have put on 5 pounds of muscle in just two weeks...if you have any questions reply to this post and I'll help you out

im a beginner aswell, even though i dont know much, this is what I somtimes do:
Chair tricep dips
dips
overhead dumbell extensions
barbell curls
dumbell curls
flat bench press
dumbel press
21's
