Answer #1

Depends on what you are attempting. If you are using a 20 lb, odds are that isnt a max out weight for you, so find what is comfortable for you, can you do 20 reps comfortably? would 25 feel a little more like you are “working out”? Then do 3 sets of those. Once that becomes easy, just increase your reps, do 30, 50… Just keep adding. Doing this will help you tone. If you want to bulk up, use heavy weights, something close to your max out. Do 1-5 reps in sets of 3, that will help you actually bulk up. If you get to the point where you can do 6 or 7, up your weight, and that will increase mass. Also to bulk up, ingest lean protines, such as fish, chicken and nuts.

Answer #2

Make sure to give yourself time inbetween reps, 5-10 minutes for a cool down. Also, work out every OTHER day, 3 times a week. It gives your body reovery time, which makes your workout more efficent than damaging.

Answer #3

Make sure you work out your shoulder muscles as well as your pectorial (chest), otherwise you will stand way too forward, or backward. Have you ever seen those guyse who walk around with there chests puffed out? Or hunched over like the Hulk? Thats what will happen. Another tip is to Make sure you work your traps, and triceps, if you only work your biceps it will make your arms still appear to be small and not as bulky. And over time your forearms may appear small in comparison to your arms, Get a smooth rod, pole or broom handle, aprox. shoulder lenght long. Tie a tough yet not bulky rope to the middle of the pole, with a weight at the very end of the rope. Now flip your arms around so your forearms are facing downwards, and your hands are palm down. Grasp each end of the rod and raise your hands so your arms are parallel with the ground. With one hand at a time but simitaniously, in a fast, upbeat mannor, wind the rope upward with just your hands.This will help build your forearms too.
