For optimal joint stability, musculoskeletal health and physical performance it is important to train opposing muscle groups equally. Would you just work out your right arm and neglect your left arm if you are weight lifting? Probably not.

It is just as important to consider other opposing muscle groups: abdominals and lower back muscles, chest and upper back muscles, biceps and triceps are just a few examples. A common muscular imbalance during weight training is the focus on hip flexor (front of the hip) exercises (leg lifts for example): tight hip flexors can cause alignment problems and lower back pain.

 Be sure to do exercises that will strengthen your hip extensors (back of the hip and butt) to help prevent this asymmetry. If you are doing some form of strength training, be sure you have a program that has a balanced strength training routine.

• Always consult a physician before beginning an exercise program. Discontinue an exercise if you feel any pain or discomfort.
