Core Sercrets Works!

8 Sep 2007 - Michelle of Massachusetts, USA writes:

I purchased this product and loved it immediately. Last year I had a stroke and I actually started doing it gradually once I was released from the hospital. I know it is the reason I am able to go to the gym with confidence. I should mention I had a severe stroke which involved a brain aneurysm. I am lucky to be alive since there is a 20% chance of living. Try this product it does work!

An informercial product that works!!!

29 Jun 2007 - Lora of Iowa, USA writes:

Core Secrets WORKS!! It is a great workout for beginners that gives results. I use body measurements vs. weight and I lost 20 inches overall (bust, waist, hips, thighs, and calves measured) in a 4 week time frame. It's also easy to do. You'll sweat, but you won't die either. I have had 2 c-sections and being on the ball is the only way that I can comfortably do ab work. This is the first exercise set I have purchased that I have actually stuck with and has given the quickest results with the least amount of time. The 'shuffle workout' mode on the DVD is great. You can shake up the routine a little bit when it starts getting mundane. I am considering purchasing a different ball than the set came with though because it doesn't seem to hold air for very long. All in all, a great program! I would recommend it.

I love Gunnar, He makes the exercise fun. The music is great and the movement is easy to follow.The funny thing is I don't lose any weight eventhough I have follow his diet advise. What did I do wrong? It's already 4 months.

One Year and Loving It STiLL

20 Jun 2007 - Ty of Ohio, USA writes:

I love Gunnar Peterson. He's a real trainer with real knowledge and experience. Most of his exercises are backed by current research. And if you read his book, this college educated pro is not just some trainer with a license. I've been with him for a year and I love his workouts. A lot of his stuff comes from a Physical Therapy background and I've noticed great improvements in my athletic ability. Gunnar's program works wonders and I never feel ill effects on my knees and back after a hard workout. I love GUNNAR I hope he never stops.

This really works......

16 Mar 2007 - Debbie of Colorado, USA writes:

I bought this product about 2 years ago and like many just put it on the shelf. Well, my friend was getting married and asked me to be her maid of honor. I had about 3 months to try and get in better shape and look good in a dress. So I got the core secrets ball out of the closet and started using it. I rotated between the ab assault and the 25 minute full body work out, sometimes I did both. I was not sure it was doing that much for me until I went to the store to look for some jeans. That is when I realized that I went from a size 12 to a size 8 in just 2 months. I was totally amazed!! As for my friend's wedding, well she had not seen me in a few months and she was totally shocked at how good I looked! I could stand up for her with pride.

Gave it a second chance and love it now!

18 Feb 2007 - Shannan of California, USA writes:

I bought the system rather impulsively on the $9.95 special about 2 years ago. I watched the DVDs but never actually used the ball. It didn't look as exciting as it did on the infomercial, I guess. Anyway, I cancelled the auto-ship program and left the ball and DVDs I had received on the shelf. Now, two years later, I inflated the ball and have been doing the workouts, and I love it! I am 5'-10" and 100 pounds overweight, so I do modify some of the exercises. Generally though, the program is challenging enough to work without actually killing myself. I've lost 10 pounds so far by adding some cardio and, of course, watching what I eat. I find the Core Secrets program a great way to get resistance training in my home on my schedule. I recommend it.

satisfaction guaranteed

10 Feb 2007 - Helen of Lancaster, UK writes:

I've been using the core secrets system for about two years now and have found it an effective way to tone all the major muscle groups, especially the abs. It does have to be combined with aerobic exercise to shed surplus fat - I alternate rebounding with core secrets plus some yoga and Tai Chi for a balanced exercise programm!- but I recommend the accelerated core training dvd for quick,visible results.

good for beginners

13 Jan 2007 - Laura of Texas, USA writes:

If you are a beginner looking for a slow paced, simple workout then this is for you. However if you are someone that has the basics down and is looking for a challenge, pass this one by. I was looking for a challenging core workout and was extremely disappointed with this product. I ended up giving it to my eighty year old neighbor.

Love, Love, Love

28 Dec 2006 - CeCe of North Carolina, USA writes:

I bought Core Secrets a few years ago, and have just recently started back working out with it. I have the original set which I normally do the 25 min. workout and I also do the Ab Assault. My new favorite one is Cardio Strength Interval (3x wk). If you feel like you are not getting a good workout by doing one DVD, then do it twice or do another one, which is what I do. Gunnar makes you want to stick with it and do more. I'm not sure why one reviewer said that you need a big livingroom because that is so not true. It takes up no space at all. Get it and try it.

Core Secrets - Yes, this works

26 Oct 2006 - Angie of North Carolina, USA writes:

The numbers: 39 years old, 5 ft 7, started at 135 lbs in August 2006. Goal 125 lbs with 13% body fat. I reached it last weekend! October 2006! Getting in shape- There is really not a big secret...eat right and exercise-everybody knows that!!! It's all about finding an exercise you actually like, so you stick with it and setting goals you can actually achieve. I have tons of tapes, but they all got old in a short amount of time...Exception: My Core secrets DVD’s. I exercise 6 times a week now picking tapes depending on how I feel and how much time I have. (8 CS-DVDs-great investment ) It was hard in the beginning, but it is all about establishing a habit-a few weeks! Now I do not feel right, if I can not exercise in the morning. To stay challenged I am increasing weights and mix exercises. After doing CS sixty times I still love it.

Is the secret out?

11 Sep 2006 - Anonymous of North Carolina, USA writes:

Gunnar Peterson is very encouraging and reassuring. His exercises feel very effective and it doesn’t take a degree in physics to figure out how to do them. I particularly like the fact that he only does one set of each exercise – I tend to bore easily and this program moves quickly since you don’t spend any great length of time on a particular exercise. He also switches back and forth between muscle groups to allow time to recover. Overall, I highly recommend the Core Secrets program to anyone interested in strength training, but perhaps a little reserved about getting started. The program will take you from beginner to advanced at your own pace and if combined with a sensible eating plan, a person will quickly see some definition where it counts!

Slow moving but I'm in fast forward!

8 Aug 2006 - Maria of Pennsylvania, USA writes:

I have tried several workout videos and thought that this one would be great for learning to use the ball. It actually is to learn the basics. I wanted a little something more fast paced where each exercise is one right after another. Excellent for the beginer and those who want a nice even paced workout!

STILL THE BEST!!!

30 Jul 2006 - Sue of California, USA writes:

UPDATE: After getting lazy for 6 months, I am now back to Core Secrets and loving it all over again! It truly is the best for targeting certain areas, and I just started last week and have done 4 sessions, and already see and feel the difference! My favorites are the Training Camp dvds. The Accelerated Training Camp is my favorite. Glad I am back!

If you're big DO buy this!!

29 Jul 2006 - Estee of Pennsylvania, USA writes:

I was a tight size 18/20. 4 weeks, I've lost 20 pounds and 4 inches EVERYWHERE! YOU MUST DO CARDIO - YOU MUST CHANGE YOUR EATING! "healthier" eating + Gunnar + cardio tapes = results. If not pound-wise, then inches-wise; if not inches-wise, then STRENGTH wise. Started with Fundamentals and then give me 20. 25 minute Full Body Workout is great and quick. The Accelerated Core Training is a great length and great dvd. After a month, I went back and redid the Give me 20... WHAT A DIFFERENCE. Always go back to where you were and see how far you have come!! My favorite is the OFF THE BALL. The "do it again" is a killer! My Abs were on FIRE after this workout. If you listen, he will give you a great workout! I feel so much stronger. walk & sit straighter. I do stairs better. My core and is stronger. Do Gunnar on Mon Wed Sat - Cardio Tues Thur Sun and you will the results!!

Works for me

22 Jul 2006 - John of Florida, USA writes:

I absolutely love this product. It seems like I tried every diet on this planet but I would lose and then gain it back...so one Saturday afternoon my wife and I were watching Gunnar's infomercial and I was sold. I decided to do 30 minute cardio plus double reps of the fundamentals and I am down one waist size and 15lbs in 3 weeks...plus I decided it was time to eat better and healthier...I am looking forward to doing "give me 20"...I would recommend this product to anybody...it is very challenging

Get a bigger ball and then do the workout

5 Jul 2006 - Roberta of Illinois, USA writes:

This workout really does target your core and in addition, other areas with the other tapes. I got in on one of the earlier sets that included all the dvds. I bought a larger ball [] and sticky mat...no slips full support. I'm a big girl that's over 5ft 7 in. I did lose a dress size in under 30 days doing the workout 5 days a week/3 wks. I think you should definitely add some cardio like the Power 90/walking. This plan with a healthy eating plan will give good results. You've got to get the fat off to see the real musle emerge. If you already exercise, adding weights will increase the challenge substantially. A buddy who exercises everyday did the program with 20lb weights while I used the 5lb and she broke a sweat.

This Program is a Keeper!

29 Jun 2006 - Sunny of Hawaii, USA writes:

My cousin gave me the Fun-damentals, Give Me 20, the 25Min Full Body Workout and the Accelerated Core Training to borrow. I love Core Secrets. I did the Give me 20 to start off and I barely broke a sweat since I do Turbo Jam practically every day. So if you're intermediate to advance, go for the longer Core workouts after you get the basics done. Turbo Jam is my cardio, but Core Secrets is my strength and stretching. Its just as they say, you can really feel your core working!

challenging and effective

23 Jun 2006 - Rachel of Illinois, USA writes:

I had a baby about 2 years ago and I'd gained 80 pounds. Twenty of those pounds are still lingering and I was already about thirty pounds overweight before getting pregnant, so needless to say I needed to lose some weight. I bought Core Secrets about a month ago, and I have to say that it is very effective in the strength and abs area, granted you will need to do other cardio to burn off more fat, but this program is great for sculpting and building endurance.I also thought that Gunnar went at a good pace, and for those who haven't worked out much, I think it was necessary for him to talk as much as he did so that you wouldn't get injured. I give it an A.
