You won't get bulky using the same amount of resistance all the time. Getting bulky, or muscle hypertrophy, requires a systematic approach to exercise. It is also essential to push your body past what is comfortable. And after a while those 10-pound dumbbells are going to be easy, and you won't get any bigger.
Getting Bulky Muscles
Getting big muscles is not that easy. Just because you lift heavy weights doesn't mean your muscles automatically get bulky. Muscle hypertrophy is an increase in mass and cross-sectional area that results from exercise -- specifically resistance training. These changes occur over time. It can take months or even years to get bulky muscles, like a bodybuilder. And although 10-pound dumbbells may be used, eventually you will get used to them and they won't force your body to change.
Overload is an essential component of a muscle hypertrophy exercise program. It refers to assigning a workout or training regimen of greater intensity than you are accustomed to, according to the National Strength and Conditioning Association. Without overload, you are greatly limited in your ability to build muscle tissue. When you first start your exercise program you may find that the 10-pound dumbbells are very challenging -- and you see some initial muscle growth. But without continually overloading your body, you will plateau.
The principle of progression is also important, and can be limited by your use of 10-pound dumbbells. Progression of your exercise program promotes long term training benefits, such as bigger muscles. Over time your exercise intensity must become gradually harder in order to stimulate positive changes to your physique. It is difficult to progress your program if you stick with your same dumbbells. Add in heavier weights to change your body.
Tips and Considerations
Athletes with big muscles don't just use one type of weight, or the same weight all the time. They continually change the exercises they perform, the tools they use and the resistance level to progress their bodies. Try different resistance training tools like barbells, plate-loaded equipment or even bands and machines to stimulate muscle growth. Also, your nutrition is key to growing muscle tissue. You need to eat slightly more calories in order to get bulky. Understanding the role of protein, carbohydrates and even fat are essential for muscle growth.
