So, why work out if you are only tearing or injuring your muscles? You have to remember that when you injure your muscles, the body will react by replacing or adding more muscle tissues to strengthen the injured muscles. This means muscle growth or an increase in the muscle mass. And, the best time for your muscles to grow is by resting or sleeping.
Try exercising different parts of the body each day. For example, on day one, you might want to exercise your chest and triceps. On day two, exercise the back and biceps. And, on day three, exercise the legs and shoulders. On each day, always exercise your abdominal muscles with sit ups, crunches and other abdominal exercises.
After day three, you should rest the next day and after that, start again with day one. Do this for two weeks and change the exercises to avoid reaching the plateau where your muscles become so used to the exercises that it will not grow anymore.
On each muscle group, try to create 4 to 5 exercises. For example, for the chest, do bench presses, inclined dumbbell presses, lying dumbbell fly, and cable crossovers. For each exercise do 10 reps and 3 sets each.
These are the things that you need to remember about muscle gain and the correct exercise routines for it. Always remember that proper execution is the key to muscle growth. Resting is also very important as well as diet.
