Hello there

I started training seriousley about 6 months ago
In the last month or so i have slacked loads, lost my gym membership and my car. But as soon as im back in the black i want to return to a weight trainign routine.

Anyway in the time i was training my shoulders and upper back bulked up well, my pecs are much more defined and with a bit more training i could have a 6-pack on the way.
Ive also put on about a stone in weight which is rising quite fast still.

BUT! my arms....they havent grown at all, infact i think they have shrunk by about 1cm.

so, recently i bought a chinning bar and i do have some weights at home but very limited.

Does anyone know what ive been doing wrong and how i can put it right? i dont want to be bulky but have arms like twigs.

thanks
