Bowflexs are great, but what you eat and when you eat it are more important. Eat only whole grain breads. Eat your carbohydrates early in the day. Don't drink soda pop or consume alcohol. Eat lots of high quality protein like salmon. I managed a gym for years and I've seen thousands of people who think they can eat something like cheesecake or drink a case of beer and then burn it off by doing an extra 50 sit ups or running an extra mile. Unfortunately, it doesn't work that way. The vast majority of the energy in the food you eat goes to keeping your heart beating and your lungs pumping. You can NEVER exercise enough to burn off enough calories to overcome eating junk food. I would recommend Sylvester Stallone's book "Sly Moves" for an in depth discussion of eating right and exercising and the psychology behind changing your body shape. Sly even has a one day a week cheat day built into his nutrition program. Nobody can eat perfectly all the time, so having that one day where you can eat whatever you want guilt free helps people stay on their plan long term. If I told you you could never eat pizza again you would probably get depressed and go off your nutrition plan. If I told you you have to eat healthy all week and you can only eat pizza Saturday night you could probably live with that. All that being said, if you've lost the weight and you still have gyno you might need surgery. What we call gyno can be fat tissue, gland tissue, or a combination of both. If you have excessive gland development, exercising won't do a thing to make your glands smaller. Only surgery can get rid of the glands. That was my case. I was able to get rid of most of my breast fat thru eating well and exercise, but my glands wouldn't go away. Of course, whether you have large glands or not, you will only benefit be eating right and working out with your bowflex.
