How heavy ur dumbell can go ?

By the way, the two exercises that u do, can hardly bring u anywhere. Try to do dumbell squat, db press and other compound exercise. But if ur dumbell only 10lbs max.... then... i would suggest u to look for a gym.

By the way, check out our sticky corner, there are lots of information on how to build muscle, including diet and exercise plan.

Since u r new, this sort of question usually u can post it in bodybuilding thread instead of opening up new thread, else u gona get flame real bad thou. Cheers bro.
