I'll assume no one is horrible enough to troll the beginner's forum.
Those dumbbells are completely useless. I curl 60s and my arms are still small.
Get a job and join a gym or
Do a lot of pullups, pushups with your little sister/backpack filled with books on your back or something, handstand pushups (against a wall) and single leg squats (or squat your little sister or something), dips or
Play football, go swimming, eat eat eat eat eat eat eat.
or buy a barbell (an olympic barbell), 400 pounds of weights, two adjustable olympic db handles
I'm gonna say this again: a 10 lb dumbbell is completely useless unless you're rehabbing a torn rotator cuff or something.
