Why you may wish to emphasize different body parts.
Sports related conditioning. If you are a runner who has trouble powering up steep hills, you may want to emphasize lower body exercises, in particular different variations of calf raises. Likewise, baseball, softball and golf all require core strength that can be gained by working your abdominal and lower back muscles. Sports specific conditioning is particularly valuable to the “weekend warrior” to help provide fitness and reduce the chance of injury.
Looking better in your clothes. As much as we may not want to admit it, we all like to look nice in our clothes. Following an overall weight lifting program with emphasis on your least favorite body parts can do wonders to balance out your look in clothes. Feel like your hips are too wide? Lunges tone and tighten the thighs while lateral raises shape up the shoulders, balancing out your body. This is just one example, the possibilities are endless.
An end to cellulite. While this is mostly a concern of women, the research is interesting. Many people have had great success reducing or even eliminating cellulite by engaging in an intensive, heavy lower body weight training program.
Reshaping your body through weight training is entirely possible. Muscle is much denser than fat, and provides a smooth surface for your skin to cover. By beginning a regular weight training program you can expect your body to look better even if you do not lose a single pound. Results are not instantaneous, of course. For the smaller muscles, such as the ones in your arms, you can expect to see results in four to six weeks, while the larger muscles, such as your thighs may take more than three months before you notice visible changes. The important thing to keep in mind is that change will happen, do not give up before you give your body time to respond. The internet provides a variety of resources for weight lifting exercises, so mix your routine up on a regular basis to stave off boredom and keep your muscles guessing.
