You can build muscle fast, but it can never be an overnight process. There has to be a serious effort and a number of other factors have to be brought into play, if you want to see major gains in muscle in short periods of time.
Diet plays a very important role in the building of muscles, and as muscles do increase the metabolism and leave the body needing more calories to burn, it becomes important to see that you eat much more than you normally do. When a person becomes hungry, the body can use muscle tissue for energy, resulting in stunting the growth of muscle. This can be prevented by eating larger quantities and having more frequent meals, so that the body is never hungry. Protein is a must for muscle buildup and must be part of diets, while the good carbohydrates like oatmeal and whole grain rice, and good fats like oily fish and nuts, can help to ensure consistent muscle growth.
Building muscle fast is enhanced if you make sure that you are exercising all the muscles groups every day and not performing isolation exercises. Isolation exercise, which involves exercising only particular muscle groups in each exercise session lead to their becoming less functional. The basic exercises like bicep curls, chest press, deadlifts, squats, and others need to be performed every day. It can also help if you reduce the number of repetitions of an exercise, and go in for heavier weights. There should also be a constant progression, so that the muscles are forced to work harder every time you exercise. Take care that you never sacrifice posture and technique, as this can lead to injury. It is also important that before you go in for any exercise routine you ensure that you go through stretching routines, so that your muscles are not overtaxed. It can also help if these stretching routines are repeated after the exercises also.
Fast buildup of muscle can be ensured if you give the body sufficient rest, so that the muscle tissues that may have got damaged or strained during the exercises have time to recover. That is why it is necessary that you limit your exercise routines to about three a week and get sufficient rest. Sleep is also important as this is the time when the hormone levels rise and this can help in the repairs to muscles.
Building muscle fast is greatly helped if you eat adequately and never remain hungry, exercise all muscle groups after proper stretching exercises, and give your body enough rest and ensure that you have at least eight hours of sleep every day.
