There are two main training errors people make that keep their biceps from growing. These are overtraining the biceps (often unintentionally) and a lack of variation in training techniques. Adding additional biceps focused workouts and trying multiple biceps exercises doesn't work.
The reason why you're not getting the biceps peak is because your biceps insertion is low to forearm.
If the weights you're lifting aren't heavy enough to challenge your muscles, your biceps won't grow. Your muscles need to be pushed to their limits to stimulate growth. Try gradually increasing the weight you lift to continue challenging your muscles.
heavy weight, volume and a good contraction exercise. for example for biceps i'd do either a heavy dumbbell or barbell curl for 2 sets of 8-10 reps. then volume on something like a hammer curl or cable curl. usually 3-4 sets of 15-20 reps. then to finish something like spider curls, concentration curls or preacher ...
Now, 15 inches might sound like a magic number, but remember, it looks different for everyone. Factors like height, weight, and overall body composition play a big role in how those 15 inches appear. For some, 15 inch arms might be the pinnacle of their fitness journey, while for others, it might be a stepping stone.
No body part grows by trashing it every day—you need to rest to let your arms recover. In the hours after a workout, your muscles lose strength and power as they heal; after 36 to 48 hours, the muscle actually gets stronger, a process called "supercompensation." Bottom line: give yourself rest.
So, which is better? It really depends on your goals. If you're looking to build bigger biceps, then you should focus on bicep curls a bit more than hammer curls. However, if you're just looking to tone your arms and don't really care about building bigger biceps, then either exercise will work just fine.
When you pause or hold a weight so the length of your biceps don't change, you target your type IIb muscle fibers, which are the ones with the most growth potential, he explains. Actively squeezing the muscle during an isometric contraction will also increase your gains.
For optimal results when starting out, consider training your biceps no more than twice a week. Two sessions a week gives your muscles enough post-workout recovery to perform at their maximum capacity during the next session.
A biceps muscle is short when it stops very high above the forearm; this is often the reason for poor muscle development. On the contrary, people with very long biceps (that come far down on the forearm) have an easier time developing the muscle.
In this muscle contraction, as you're flexing the elbow, you can measure your bicep gap. If you can fit more than 2 fingers in the gap between your bicep and your elbow, you may have short biceps!
The average bicep size is around 13–14 inches for young adult males with big biceps measuring 15+ inches. That said, some professional bodybuilders' biceps have reached 20+ inches. Therefore, with regimented training and nutrition, 18-inch arms are achievable.
The Scale is Going Up
You might not see your biceps pop right away. The first sign that you're building muscle may be an increase in body weight. The number on the scale goes up because muscle tissue is denser and heavier than fat. Therefore, it takes up less space for the same amount of weight.

Protein is important, to be sure. After all, your muscles are made of protein, and your body requires adequate protein in your diet in order to have the building blocks it needs to build up muscle mass.
If your goal is endurance and lean muscle, use a lighter weight and perform one to three sets of 12 to 16 reps with at least one day of rest in between. For maximum results, switch up your workouts. Don't do the exact same routines every session.
Typically, muscle mass and strength increase steadily from birth and reach their peak at around 30 to 35 years of age. After that, muscle power and performance decline slowly and linearly at first, and then faster after age 65 for women and 70 for men.
Your traps might not be growing due to a few possible causes – all of which are common if you have little experience in weightlifting. You might not be stressing them enough with the right lifts to see increased muscle mass. That means you might not be using the best exercises for trap growth.
