I'm 31 and just started a new workout program. It's pretty intense, and I make it a little more by adding additional workouts, and by working out 7 days instead of the recommended 5. Its an online program called BodyRock. The website is www.BodyRock.tv I am VERY happy with it. However it's not for everyone.
I like that it provides a daily (5x a week) workout that is different almost every day. There is NOT a video I have to follow along with but instead a 5-10min instructional video that shows you the proper form, and easier variations for beginners. Most of the workouts are interval training (google HIIT High Intensity Interval Training) lasting anywhere from 10-60min. Most of the workouts are 15min or less. There is very little equipment that you HAVE to buy but if you wanted to keep up with the Jones's you'd spend about $150 on equipment. I can do all of these workouts from home. I don't have to go to a gym and workout if front of other people. My face tends to get bright red when I'm working out and it makes me VERY self conscious when I work out in front of other people keeping me from putting forth maximum effort.
I also like that she offers a diet and nutrition plan. Portion control, and low carb. You earn the simple carbs (bread, rice, potatoes, pasta, etc) you eat through a workout. You can eat complex carbs (qunoia, oats, couscous, etc) with your meals but make sure they are in small portions. 5-6 small meals a day with one portion (size of your palm) in lean protein (chicken, turkey, fish, FF cottage cheese, nuts, beans, etc), and 2 cups of fruits and veggies. I've eaten more salads than ever!! The website has many recipes and the online community is great for providing ideas as well.
I haven't really lost much weight, but I wasn't trying to. I have lost A LOT of fat, and can see my muscles! I'm very close to a 6 pack!! I also use an app on my phone called myfitnesspal there is an online version of this www.myfitnesspal.com if you don't have a smart, i, droid, or other phone that uses apps. From everything I've heard losing weight is 80% food and 20% exercise. If you're putting the wrong things in the body you won't be able to lose the weight.
I do not like all the jumping, so I modifiy most of the workouts to make it easier on my knees. It's not hard but I wish that the there were more workouts she offers without jumping. Also the person that runs the workouts (Zuzana Light) was a previous adult star. So there is a little too much focus on her "ladies" and I thought this would take away from the workouts themselves but...when I started doing the workouts I focused less on her enhancments on more on how GREAT my body was starting to look.
Like I said this isn't for everyone...but it's GREAT for me. I hope you're able to find a perfect fit for you too. I am, and I feel healthier than I have EVER felt in my life.
My SIL loves sparkpeople.com. It helped her lose over 30lbs. It is also an online community that gives recommended meals and I think (but maybe not) workouts, plus a calorie counter. I have not used or known anyone personally that has used weight watchers but I think it also sounds like a GREAT program!
GOOD LUCK!!
