Men and women have different body types, so it makes sense that we should focus on different types of exercises.  To get fit and toned, but keep the long and lean look, personal trainers Kristal Richardson and Tracy Anderson offer tips and alternatives to exercises that should be avoided.

Kristal Richardson lists five common exercises that are more harmful than helpful, and what we should be doing instead. [The good news: No more sit-ups (Chicago Tribune)]

• Sit-ups lead to neck pain. Try bicycle crunches instead.
   
• Weighted squats will bulk up your bottom and upper thighs.  Do lunges intead.
   
• Behind-the-neck shoulder presses can cause permanent damage.  Seated shoulder presses are better.
   
• Straight leg push-ups stress the neck, lower back, elbow and shoulders.  Do knee push-ups.
   
• Standing dead lifts result in bulky back, leg and rear end muscles. Try leg kick-backs instead.

Tracy Anderson (Madonna's and Gwyneth Paltrow's personal trainer) also recommends different exercises for women.  I recently picked up her Mat Workout DVD and love it.  Her method includes working out accessory muscles to avoid bulking up in any particular area.  Her most important tip for not bulking up is don't use weights heavier than 3 pounds.
