Little weights are good, like 5kg-8kg. Just do different kind of moves with them, like u go on ur back at the ground, put ur arms straight with your body on the floor, start pulling off the weights next to your legs at the floor, not on the ground, then slowly back, dont let it touch the ground, so on. Also one good is that you stand up, put ur arms like this, i dunno how to explain: (arm)-|-(arm) (body) And lift your hands up in the air, then slowly to the same position u started, and to air. I hope I made SOME sense.
