Ah, yes the biceps. I know that some people have an easier time getting certain muscles to grow over time. For me, my biggest problem was the muscles that require those isolation exercises to grow. I am usually pretty lucky to see growth on those big compound lifts. For those who do not know the compound lifts are the ones that involve your whole body or multiple parts of it. For example, squats and deadlifts would be compound lifts while the isolation lifts would be something like preacher curls. These isolation exercises would always lead me to a standstill as far as progress was concerned. Recently I was reading some tips on the internet. I found someone talking about doing 21s. 21s are named for the amount of reps that required for you to complete a set. Even better, you do these with a barbell so you are going to be lifting bigger. Combine this bigger lift with higher reps and you get growth. You also get pretty sore so check the ego at the door and start small.
I have really found some great success with this and this is how you do it. You bring the barbell up from the bottom to halfway up and that is the first 7 reps. After that, you go from the halfway position to all the way up and this would be the second 7. Finally, you do 7 full motion curls. I don’t really recommend that a beginning weightlifting even attempt it. You have got to get some growth and experience in lifting to your biceps before you do this. However, once you get to the stage where you can do this, you are really going to get some amazing growth in your bicep muscles.
