Are you looking to improve your body? Silly question, isn't it? I think almost all of us have an area or two (or three or four) that we'd like to improve. While you can't lose weight in certain spots, you can target and tone your problem areas. Here are eight tips:

• Want to lose that muffin top? Try sprints, interval training or other intense cardio exercises. Also, when doing crunches, aim for constant tension in your abs. Pilates is also great exercise for your core.
• Trying to lose weight all over? Be sure to mix up your exercise routine. Try doing something different twice a week. Adding fast bursts of fitness to your routine can help, too. And don't forget strength training!
  
• Looking for a better bottom? Plyometrics are great for your glutes. Hip extensions and step-ups are also good choices.
• Want to shed back fat? The seated row and wide-grip lat pull are effective for this area. But don't forget the cardio. Also, it's a good idea to work the opposing muscle group so work your pecs as well.

• Trying to lose that arm jiggle? Make sure you're using enough resistance/weight -- you should feel somewhat spent after 10 reps. Also, try undulating training -- using high reps and a lower weight one session, and fewer reps with a higher weight at the next session.
• Don't want to burn out? Build up gradually so you don't burn out. And pick an exercise that suits your mood.
  
• Worried about getting bored? Exercise shouldn't be boring. Make a game out of your run or bring a friend along as a coach.
  
• Want to get the most out of your workout? Increase your intensity and aim for varieity. Also, look for opportunities throughout the day to get in just a bit more exercise -- such as taking the stairs instead of the elevator.
