Give me just two minutes of your time and I’ll tell you whether or not the 30 Day Shred is worth your time. We checked out the exercises, side effects, clinical support and customer service. We also read as many user reviews as we could find. Then, we summed it all up to give you the bottom line.

What is the 30 Day Shred?

First off, the 30 Day Shred is a workout DVD from Jillian Michaels, celebrity trainer. According to the fitness guru, “you can lose up to 20 pounds in 30 days” using this one 20-minute program. You will need a set of hand weights and a mat if you have harder floors. There are three exercise routines included.

The program was created by Jillian Michaels in 2008. It is available on websites like Amazon and her official website. We like that the workouts are short and it costs far less than many comparable options, but read on…

Pain – “Is This Gonna Hurt?”

The first issue we found with 30 Day Shred was pain. “Working out is all about making your body healthier and burning more calories,” says our Research Editor. “It’s not about pain or injury.”

“I always experienced severe pain after the routine… even after replacing this workout for an entire month,” said one user.

Another shared, “I’m not sure every person who experiences knee pain after this DVD is to blame for improper form.”

On the other side of the discussion, some felt there were small issues that led to the pain.

“When you’re exercising watch your form to make sure you’re not injuring yourself. After I did this my knee pain went away and I’m all good,” was one suggestion.

One more said, “Calves are still sore, but not crazy sore like the first 2 days. I slapped some Tiger Balm on my knees beforehand along with wearing a knee brace on my left knee. It was great! I could get through the workout without a whole lot of pain.”

Injury – “Is it Safe?”

Another issue we stumbled upon was reports of injuries. There were more than a few in the reviews we read.

“Every time I do this work out, I inevitably end up with some kind of injury, either my knee or my back,” was one experience.

As another user said, “I think the repetitive movements in the video caused inflammation and rather than stopping and letting them calm down, I kept pushing myself and it resulted in injury.”

Others didn’t notice any issue with injuries with modification.

“I have a very weak knee from an injury, and I am finding that doing this workout at a slower modified pace and stretching level 1 out to 1 month instead of 1 week, and following everything Jillian says about how to position the knees so as not to hurt them, my weak knee is actually being strengthened,” one user offered.

A viewer also said, “I think doing these every day will backfire on you and sabotage results unless you are already really strong and in tip top shape. The last thing you need is injury or burn out half way through.”

The Science – “Any Real Proof?”

At DietSpotlight, it’s the science that seals the deal, either way. In this case, there is evidence that exercise is healthy and a critical part of weight-loss. That doesn’t mean the 30 Day Shred is any more effective than walking or using another DVD.

The Bottom Line – Does the 30 Day Shred Work?

Have we already decided to order the 30 Day Shred? Well, we like that Jillian Michaels supports exercise for weight-loss, but we’re skeptical about recommending this specific workout. There are reports of pain and injury that we can’t just dismiss. Plus, it was created in 2008 and advances have been made in the years since then.

If you want to use exercise to boost weight-loss that is an excellent option. But, you may want to add a supplement that’s shown to help boost metabolism and fat loss in the process.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It’s formulated with four, strong ingredients backed by clinical testing. User reviews are out of this world and we found no reports of harmful side effects.

It’s also amazing that the makers are so confident in the formula that they’re offering a Special Trial Offer.

What You Should Know

Nowadays there are all sorts of professional fitness trainers and exercise gurus coming out with books and DVDs on healthy weight loss. Jillian Michaels is one of these experts. You may even recognize her name from the hit NBC reality series, “The Biggest Loser.” She worked on this show to assist many men and women with weight reduction. Now she has a DVD out entitled “30 Day Shred.” The official pitch is that it helps you drop up to 20 pounds in 30 days. With the 30 Day Shred DVD, the dieter learns how to do circuit training and build lean muscle mass. There are three twenty-minute circuit-training workouts, to help you burn off plenty of calories and strengthen your body. These fitness regimens are based on Jillian’s unique approach, which is 3-2-1 strength/cardio/abdominals. To break it down more, you start with three minutes of strength training, and then do two minutes of cardio, and then one minute of ab work. Before you get started, there is a short warm-up. Once you finish the workout, there is a stretch and cool-down session.

jade (Verified User)

1. do i need to do this everyday ? because after doing this (it’s the first day i do it) it’s difficult to go up stairs !

2. if i want maximum resaults i should do it everyday ?

3. after how many time can i get good resaults ?

Maribel (Editor)

Hi Jade!
1. It’s okay to have rest periods between days. The 30 days don’t have to be consecutive and should be mixed with cardio training for best results.
2. For maximum results, you should give your body time in needs to repair. For best results, give yourself some rest days, so your muscles can recover and grow stronger.
3. Result vary from individuals to individual, for best results combine your exercise routine with a healthy diet and make sure to complete the 30 days, to the best of your ability.
Wish you the best of luck!

Maribel (Editor)

Hi Carrie! Each workout is designed to be done for 10 days before advancing to the next level. So, once you have completed 10 days of level 1, you can go ahead and go to level 2. Best of luck!

Yeah but snacks and junk food TASTES SO GOOD! I aws in the supermarket, saw that Haagen Daazs was 2/$7 and I got happy! The programming to accept fatty foods runs very deep.

allison (Verified User)

  Why is this not working?
Collette (Verified User)

Does anyone do the diet plan with the 30 day shred? I have heard a lot about it but not found anything on the internet. I am on day 3 of level 2 of the 30 day shred. Hard to begin with, got rid of the muscle ache by day 8. Have no more back ache, feel great but have put on weight instead of loosing. I am still determined to stick to it till the end but does anyone have any explanation or ideas why I aint loosing??


your diet should be low in fat and calories. eat fresh vegetables and fruit as well small meals with protein and carbs every 3 hrs to keep your metabolism up.

30 Day Shred
Tara Lynn (Verified User)

I have been doing 30 Day Shred for a couple of weeks now and am seeing results! At first was so sore had trouble walking up the stairs at work, but now it is much better. I am switching between Level 1 & 2 each day now.

  This dvd is highly recommended by me for both men and women.
James (Verified User)

I have at least 3 decades of prior training. I am an ex-military police, trained in boxing, powerlifting, and body building. Now as a 60 year old fit male, I must commend Jillian for this very effective training video. It has helped my conditioning, and allows me to get in a quick and efficient workout. I am seing a feeling results after just a few weeks. This dvd is highly recommended by me for both men and women. My only advice is to get up off of your rear end and do it!

  When should I start seeing some results?
Christine (Verified User)

I have purchased the 30 day shred & today is my 4th day of doing it. When should I start seeing some results?

  Loved the product.
sue migonis (Verified User)

are you supose to feel like you want to throw up after you excersise? i did level one and i really feel like i want to puke.


I felt that way also but my second day I slowed it down a bit and did fine ,


I have been doing Jillians 30 day shred for 3 months and can finally see my abs! I did the workouts 4 times a week but once i got my endurance up, I did 2 of the workouts at a time. (usually 1 and 3) Now I’ve bought her Ripped in 30 and it has 4 workouts with her same 3-2-1 method. But this dvd is much much harder…


Hi… Did you lose inches or weight? Also, what was your starting weight? Are you following a diet? …. Trying to get motivated!


start with the modified version and work your way up to build endurance. I did that& it felt good, a bit sore, but not pukey


I did too. I almost gave up but went back two days later and it was easier. I take a few breaks during workout.I’m sure it will get easier.I am trying to get motivated right this minute!
