Getting Bigger Arms
If you want to get bigger arms, then you need to do bicep workouts like curls with dumbbells or barbells. Generally, if you want to gain an inch in diameter, you need to gain about 10 pounds. The key to getting stronger more muscular biceps is by pushing your muscles through extreme resistence. When you workout, your muscle fibers actually tear up. When this happens, your body automatically starts to repair it, making your muscles stronger. This is how you build muscles.
As for biceps, a great way to work them out is by using the pyramid rep technique. Basically, after you’re done warming up, you will choose a weight that you an only do 6-8 slow reps with. This will be your first set. Each set following this, you will increase the weight and do 2 less reps. So for the second set, you will do 6-8 reps. You will do this for 4 sets. Your last set will consist of curling a weight that you can only do 1-2 reps. The reason for doing this is to force your muscles to grow by causing it to tear. It sounds bad but this is normal. The key is to be consistent.
