Focus on working out your largest muscle groups. Concentrating your efforts on large muscle groups such as the back, chest and legs will help you to build muscle faster. Exercises such perfect amino reviews as squats, pull-ups, bench presses, and dips are ideal for this. These kinds of exercises are generally more intense, and will help boost your protein synthesis.
Short-term use of creatine supplements can help you build muscle with minimal risks. Creatine plays an important role in your body in that it is required to produce ATP, a basic and vital form of energy. Your body cannot function without ATP, and lack of creatine can cause muscle problems. Having a higher level of creatine will enable you to train more intensely, and for a prolonged period of time.
If you cannot get to the gym for some reason, do not skip your workout altogether. You can simply do chin-ups, pushups and dips in your home. Even with all of the fancy equipment at the gym, they still remain the best forms of upper body building that you can do.
