I have bowlegs. It is quite frustrating because I cannot do exercises that isolate and tone the thighs (lunges, squats, etc). When I do squats, my pressure/force comes from the calves and the knees, but not the thighs. Reason being is that the legs are not properly aligned, and pressure/force cannot go up to the thighs. It even hurts when I do squats because they involve bending the (crooked) knees. Are there any alternative thigh exercises?

I am 18 years old and I am determined to lose a few pounds and tone my body by the end of May. I just began running and I'm starting off by running a mile and hope to work up to a four-mile run four or five days a week. My diet is generally a bowl of cereal in the morning, and a turkey or ham sandwich with some type of fruit and a bottle of water. Dinner is something different every day, but usually healthy. I also have been doing an ab workout for about seven minutes after I run. Is what I'm doing effective? What are your suggestions?

I know most of us have seen the ads to buy various muscle toning equipment that uses electric pulses to "build more tissue" (hypertrophy), and I was wondering what you thought about this way of "toning muscle." Also, if you knew where else I could go to further my research on these sorts of devices?

Thank you very much for your help in advance.

About five days ago while I was doing step aerobics I stepped down incorrectly and injured my foot. It turns out, after seeing the doctor, that I cracked a bone on the outer side of my foot and will have to wear a boot cast for about four weeks. My question is, since I can no longer do aerobics, what other kinds of exercises can I do to help me lose weight? I already do weights, abs, and any other type of leg exercise that don't involve me standing, but I don't feel that this is enough and since I am prone to gaining weight easily, I really want to do as much as I can but in a way that I don't aggravate my injury or make it worse.

Do you have any suggestions for me on losing weight? I feel so intimidated going to a fitness center because of the looks I get. I really do. It seems like an individual has to be thin to go into fitness centers now-a-days. I should say some of them are that way.

Can you tell me a way to figure out my basic metabolism?

Why is it I can always run a greater distance on a track than I can on a treadmill? On a track, I can run five or six miles, but on a treadmill, I can only go a maximum of three or four, then I tucker out. Is it because I get more bored on a treadmill, or is there a more physical explanation?

I have started spinning and I absolutely love it. Currently doing it about 3 times per week. My boyfriend says that spinning will cause permanent damage to my female genitalia, such as damaging the nerves, leading to reduced sensitivity and ultimately impeding my enjoyment of sex. I always wear the appropriate padded shorts. Is this true or not?

I have heard that if you exercise/work out in the morning before you eat breakfast that it will cause your metabolism to increase throughout the day, helping you to burn calories. Is this true?

I swim three times a week for 40 minutes and sauna for 15. When I come out of the sauna my face is beet red and stays that way for about 1/2 hour — is this a sign of something wrong? Also, is it bad to work-out (sit-ups, push-ups) in the sauna?
