Your muscles should be proportional in size to each other. This gives them a more defined look – which means that you look ripped. The growth of your muscles is affected by your skeletal structure: Your height, girth and bone density put a limit on how heavy your muscular structure can become. As far as possible, resist the temptation to work only your vanity muscles (the ones you tend to check out in the mirror). Give all your muscle groups equal attention with a well-balanced routine.
Training plateaus aren’t as bad as they are made out to be. They are simply an indication that your body has reached a muscle-growth limit. Such plateaus are caused by your body’s limited supply of testosterone. Your body puts a temporary stop to muscle growth when it channels your T-juice to fuel your other important bodily functions – like your sex drive. A permanent plateau also hits when — because of skeletal limitations — your body is unable to add any more muscle mass. These plateaus help you avoid injuries; they prevent you from overworking your body.
You only need to take your cue from professional athletes such as football players and MMA fighters. Their lean, well-proportioned muscles are not only for show – these muscles are able to deliver peak performance over extended periods of high-intensity activity.
Sports movements consist of a variety of movements at different planes, not only up and down or side to side. Lean, well-proportioned muscles give you better motor control – allowing you to react faster and with greater functional strength.
Your body’s natural limitations on muscle growth may be compromised in two ways: A common workout mistake is allocating a disproportionate amount of training attention to specific muscles. This may result in them becoming over-developed – while the neglected muscles remain under-developed. The abuse of anabolic steroids also pumps additional testosterone into your bloodstream, resulting in muscle growth which your body would otherwise have been not capable of. Bulky, over-developed muscles may lead to muscular imbalances, which limit your movement, and ironically, your functional strength.
