Do Target Exercises work?

While I still have another 50 pounds or so to reach goal, I've noticed my legs are very slow to lose weight.  I can't decide if they look more like tree trunks or sausages!  So I'm wondering if exercises targeted for the legs will help.  I know that part of the problem is just how I carry my weight, but is there something I can do.  I exercise using a recumbent stationary bike 5 times a week and swim at least twice a week.  I have bad knees so can't do exercises that stress them--as it seems most leg exercises do.  Any suggestions?

Sally, The answer is yes and no.  Unfortunately you cannot target weight loss to specific parts of the body.  Fortunately you can target specific parts for toning and addition of lean muscle.  with 50 pounds to go until goal, you should continue working total body with weight loss in mind...cardio as you've been doing and weight/resistance training (as you're able given physical limitations) with low weight and higher reps with multple sets.  Doing so, your workouts will be geared toward fat burning...and in adding in the weight/resistance training (where you can target your legs) along with your cardio, as you lose inches and pounds over your entire body, you'll have the added bonus on toning and firmer muscles.

Unfortunately, target exercises do not work.  Current scientific research does not support its use, and does not make sense physiologically.  Exercise does not cause more fatty acid release from the fat depots that are directly over the muscle.    The only time where training specificity actually is helpful is when training certain muscles for a certain activity, just not when losing fat. The negative energy balance (calories being burned is more than calories coming in) that is created by regular exercise is the most important aspect in reducing total body fat.
