I really like it stared 2 weeks ago

posted Oct 23rd, 2017 4:41 am


I bought this program about 10 years ago and tried it for about 2 months along with a good diet program and I didn't lose a pound. Little did I know that I had a thyroid disorder which was causing me to not lose any weight. Now that I have my thyroid under control with medication and diet, I am starting the program again. I have lost 12 pounds in 2 months! That's a lot for a thyroid patient! I love this workout! Debbie is a joy to workout with, in my opinion! I love the fact that everything feels so slim and strong. I still have a ways to go, but I am definitely going to stick with this program!

Hello i can honestly say i also had seen the infomercial on a sleepless night and got it.I did do the 7 day express program to a t and lost inches the first week,on the second week i was losing my pj pants while walking was also using the slimming formula.I stayed on ramp it up coz coudnt do burn it up it took me 3 months to go from a size 18 to size 3 (wasnt even that small in high school)kept it off for bout 5 years but now got the weight back.Wanting to do it again but the music is real boring .It worked wonders for me and getting the courage to do it again but like i said i took the slimming formula was doing ramp it up 6 days a week and was following the michi laddet to the bone.Was also doing slim n 6 pack 7 days a week.I am not a beachbody coach simply a desperate to lose weight .I also have hip hop abs but find it boring .When i bought it they offered a 30 day money back guarantee dont know if they still do but the choice is yours .Good luck to all on your goals

It's okay! To be honest, the DVD has been a little exaggerated if you ask me! All these pics of people losing half their dress size!! I'm on my 5th week and I always put my best in, but I've hardly lost anything. I feel better in myself but all I've lost is an inch on my waist! A little confusing as I've just spent £66 on this and can really say its been worth that! I expected better results.

Ordered this program a long time ago. Used it then got bored and switched to another one. I fell off the wagon and decieded to pull out all my old programs and pick one to start with again. I did my first workout and will do the second one today. I am SORE. I only have about 10 pounds to loose. So here I go!

You guys are going to do great with Slim in 6 in you just follow the directions you WILL get the results. But remember that the results you get is 30% of the hard workout you do and the nutrition you eat is the other 70% so make sure you eat clean. I have many Clients that have gotten great results with this one and love the fact they can stick to it.

I have tried LOTS of diets. I'm a infomercial junkie. I'm 5'10 and 150, so i'm not a crazy weight, but I feel like I have been trying to lose 10 pounds for 10 years. Slim in 6 is the only program I keep going back to. In college I did it to a "T" and it really worked. I can't say I lost 30 pounds, but I could tell a significant difference. The diet is pretty strict, but if you can stick to it, it pays off. The workout videos will build your strength. I lost my videos, and I liked it so much that I am getting it again.

This will work if you have the time to invest (one hour a day, 6 days a week) and do not bore easily doing the same workout videos repeatedly.

I made it until the 5th week and then I got really sick, keeping me from exercising for a week and a half. I tried to continue doing Burn it Up, the last video in the series, and couldn't. I didn't have the heart to start with Ramp it Up again, so I am moving on for now.

The Good:
- Lost about 8 inches total - and I'm 155 and 5's when starting. Just had a baby and helped tone me up and I lost a lot of inches around the waist, stomach, and butt.
- The repetition helps you master the moves and you can see yourself progressing. All the videos build on each other, and so after 6 weeks you get a chance to perfect each move.
- Debbie is really good at teaching forms. I've been doing lunges and squats wrong my whole life!
- I felt strong and my clothes were loser within the first week.

The Bad:
- I only lost 2.5 lbs, but I did look better and clothes fit. I'm assuming it was because I was gaining muscle.
- I've never had knee problems before, and by the end of the 4th week I was noticing "clicks" when I bent my knee during the workout. There are lots of squats and lunges which can be hard on the knees. But no jumping and high impact moves, like many videos.
- BOREDOM! A lot of the moves build on each other, so it's easy to get bored. The results and seeing myself progress countered this.
- The music is horrible. I started playing my own music over the video to keep my sanity.
- An hour a day can be a lot 6 times a week.

Overall, this produced more results than I have ever had from any other workout. I plan to go back to this after I take a month break doing the shred.

i just purchased this program, but i didnt get anything extra, like no supplements or additional work out videos, i just purchased the $60 basic dvd set.. does anyone know if the results will still be good??

I saw the infomercials and said if it doesn't work I can sned it back, what is there to lose. I lost 20 lbs and kept it off for 3 years. I then went on to purchase the other Slim n 6 products--Slim Series and 30 min workouts. They are a lot more intense and they ensure you will not plateau. It was the only workout where I lost inches in my hips consistently. My body is constantly challenged and muscle continues to tone and I feel stronger everyday. I love this program.

This is a great work out video!! 2weeks into the video and i can feel my 6 pack abs!!! I just need to burn that 8% belly fat! If your looking to lose weight or tone up this is the right video for you and its quite easy

ABSOLUTELY LOVE THIS PROGRAM! You'll get out of it exactly what you put into it! I'm married, have two little boys and work full time...I get up at 4:45 every morning to devote my health and well being to this program because it does work! since using this program, I'm one size smaller than I was before I had my first child.

OMG this saved me for real I was yo yo dieting for years and stayed fat for 3 years straight failing all exercise and diets.I hate to exercise but ths regimen was so awesome and really motivated you as well as targeted all problem areas. I know it may seem pricey but it is so worth it.I went from a tight sz 12 and now I am a loose 8 in just 3 months.I didnt have to starve myself either. My goal is to get back into my sz 6. I'm 5'8 so I don't want to get to skinny but just a healthy slim look. SlimIn6 really works !With diet and exercise you will be back in shape before you know it.

From a guys point of view...

I was slightly active but not in shape by any means - 35 / 5'7 / 185. So I started using P90X. Holy crap, a week into it and I just couldn't hang. So, on the advice of the P90X fitness guide, I began Slim in Six to get ready for the more challenging program.

The first week of Slim in Six was fairly easy but left me sore. Second week, much easier and a lot less sore. Started "Ramp it Up" (the second portion of the routine) on the third week and it was a bit harder making me sore once again. Now I'm in the middle of the fourth week, continuing with "Ramp it Up" and so far have lost about 7 pounds and feel much stronger. Around the beginning of the third week I was struggling to finish the routine and now it's become quite do-able. Happy to see and feel results, can't wait to finish and move on to bigger and better things.

Granted it's focus is on your lower body and for women, but that seems like a good place to start for folks new to an exercise program. Personally, I like Slim in Six, glad it was recommended to me and would recommend this program to anyone interested in a quality workout - minus the gimmicks.

Tjhinking about getting this - will it really slim and firm my belly area - will my abs show back up?

posted Sep 20th, 2009 6:20 am


I love it. Takes me back to high school gym class...wish I had worked harder back then instead of now. I'm not doing the fast or really following the diet, just cut back on portions and make better choices. Currently, 3rd week now and still doing ramp it up. Also, not doing 6 days a week more like 4-5. Can't do all the leg lifts either and have still in 3 wks lost almost 6in. from my waist. Gained two pounds which doesn't thrill me, but I measure daily. Some areas staying the same, some changing a lot. Clothes fitting better too. Don't rely on the scale. Some say her workout is a bore. If you like fancy moves it will be, for me it is familiar stuff from high school (1987). Very basic and effective.

I just bought it and I am starting the two day fast, I ate less yesterday and today is my first day of fast and already 2lbs down! hopefully the other 50 will come off too.

posted Sep 4th, 2009 12:37 pm



I like the slim n 6 series. It's easy and fun. I have only been using it for a few weeks and already have results, my belly and thighs. Lost about 2 inches in my waist and 1 1/2 inches on my thighs. Hopefully I will be back to normal soon after having 2 kids.

I think this sounds like a great DVD and I am planning on giving it a try. I like the idea of being at home to exercise and the program is very affordable.
