Yeah, I want to gain some muscle, but all I have access to is some dumbells (I can set whatever weight i could ever imagine though). Basicly I dont know any lifts or anything other than just bicep curls (the only thing I've been doing so far lol).

So, ISO some lifts I can do to build strength using simple dumbells

try google
like, 'workout tips with dumbells' or something

Do some deltoid and tricep shit...For deltoids, set a low weight (3-10, maybe slightly higher if you are very strong), and start with your arms pointing down, and raise them up to over your head, withour bending your elbows. You can go in most directions and it will help.

yeah, definetly make sure you dont start out too heavy, you'll pull sumthin. and are u looking to do just upper body or lower body aswell?
