# 4 Front and Back
One of the keys to gaining muscle is to keep your body balanced. The best way to do this is to work your muscles in pairs of pulling and pushing exercises. For example, when you work out your chest, you should also work out your back. The main reason for this is that opposite muscles are usually the secondary muscle group in compound movements. This is critical, because working out your back can aid your bench press, allowing you to lift heavier weight and, in the end, see greater results. Balancing out your muscles by working your front and back will let your stabilizing muscles take on more of the work during your lifts and will help you boost your strength. Keep in mind that this method is not just limited to your chest. It can be used all over your body with exercises such as front and back squats, and bicep curls and triceps extensions. Working out the front and back parts of muscle groups will let you see a greater increase in not just your overall strength, but in your body size as well.
