Even with regular work-outs, weight gain may be due a lot of factors such as: hormonal imbalance, as side effect of medications you may be taking, fluid retention from excess sodium or existing medical conditions such as with the thyroid. It would also help to know your body mass index and the daily calories you should be having. Asidefrom exercise, proper diet is also important.

Hey - I've done alot of research into this and was told many times that a person will put on muscle before they start to burn fat. While that can be annoying, in the long run it is much more effective, as muscle burns way more calories than fat.
Of course, if you haven't cut down calories you will gain weight as well. You can work out as long and hard as you want, but you will always gain weight unless you are burning more than you are taking in.
For years I ran and did weights. I loved the definition I got in my upper body, but always found that if I did leg weights, my legs would get bulky almost instantly. This frustrated me to no end, until I finally worked with a Pilates trainer and she said I was overusing those leg muscles that were getting bulky. I learned different excersises with her that toned for great results. I highly recommend trying Pilates, but if not, is there a trainer you can meet with to work to get the exact results you want? Most gyms offer a free training session or 2. Good luck!
over use and the muscles would get bulky...makes sense i guess. how long though did it take you to see your muscles lean out and fat loss begin? it frustrates me to no end, as soon as i start lifting although i'm using low weights and more reps my muscles get big. it makes me feel better knowing that its something that could possibly go away some.
