Not for the faint of heart; no doubt excellent if you are young and have good building blocks re: your body. I crippled myself doing the lowest level for 4 days straight, this even while trying to modify the moves. If you have bad knees, hips, or ankles/feet, be very careful about doing this video. If you can repeatedly jump up and down on a hardwood floor, give it a go. Does get you pumping, but not worth it if you then have to stop doing anything but stretches for 2 weeks while your knees heal.

i was a bit intimmidated when i purchased the dvd because i have seen how hard jillian is with the contestants on the biggest loser. I am very happy at the results i have been getting in the las two weeks that ive been doing the workouts. I have only done workouts one and two, but boy do you sweat. I like that it is only twenty minutes long and very effective. i would recommend this to anyone who needs a challenge and wants to try something different. she is very good at explaining the workout and giving you the option of following the begining or advanced workout, which helps out in the first few days.

These workouts are great. Basic moves in a short period time. The warmups and cooldowns are short, but effective. I feel challenged throughout the workouts and energized afterwards. I have done the workouts for the past five days and will continue to do them every day. No change in the number on the scale, but I can definitely see and feel that my body is changing. Wonderful, wonderful workouts and a great, motivating instructor! I HIGHLY recommend these workouts...for anyone!

I was skeptical bc it was a dvd.....but its so great!!! In live in NY and its too cold early in the morning this time of year to go out to the gym (and evening workouts....never "workout" for me). So a dvd in my apt was the solution. Its only the first week, and Ive only done level 1 but Im sore. I typically worked out a few times a week at the gym so Im no couch potatoe. The best part is its only 20 mins and the time flies by. I plan to continue level 1 until I make it through and do every move!!! (My arms strength is a lil lacking) Once I do Ill do it another week and move to level II. As for music...I nvr noticed it, Jillian talks the whole time (which isnt much time at all), I like her though.

I love this DVD. I'm 49 and 40 lbs. overweight and was looking for something challenging and easy to follow (not easy to do - easy to follow). This is it! I like that there are 3 levels. I switch between level 2 and level 3 so I don't get bored and save level 1 for days that I don't feel like working out (It's still a good workout but in my head I'm telling myself just do it - this is nothing!) AND I WAS starting to notice big changes in the shape of my body but unfortunately I have to start all over again from the beginning because I let things get in my way over the summer. Definitely try this if you are looking for a workout DVD. The only thing I don't like is the background music/noise. Yuk.

This DVD is not good for beginners. There are no low impact options and Jillian's "push through the pain" philosophy is dangerous. I would recommend this for intermediate or advanced exercisers.

This Dvd is amazing. . . I have enjoyed working out to this. The 20 minute workout is very intense. You know that Jillian knows what she is talking about! I've done the video 2 times a week plus a variety of different work outs. I have seen some amazing results!I would recommend this to EVERYONE! It will Kick your butt and get you into shape. If time is your issue then this is the best work out you can get in for 20 min!!!!!!

This is a killer workout. I made it 10 days with level 1 and 3 days with level 2 before having to stop. My knees are killing me; I could barely walk afterwards. Sweat like a pig and no weight loss or inch loss. Will probably need a very strict diet to see any results.Jillian is very pleasant to listen to and very motivational. I believe in her workouts... just not for anyone with knee issues. If you are young, strong, can take constant pounding on the knees, then this workout will do you good. It is a challenge and a very difficult workout. But if you have any issues with high-impact workouts, or workouts that are killer on your knees, then avoid this one.

This is my first experience with Jillian Michaels, and I'm hooked. I'm about half-way through the 30 days and I love it! I've lost 5 pounds and 1 1/4 inches. My body is changing, my energy is vastly increased, I'm sleeping better at night, and just yesterday I purchased two more of her DVDs. It's totally worth the buy.

I work out on a regular basis, and this DVD challenged me far beyond what I had been doing- and I started with the beginner level! The workout may only be 20 minutes, but it will be the longest 20 minutes of your life. This is an excellent fitness tool for people who are often pressed for time and are looking for a quick workout, such as on a lunch break from work. My one caution is that if you are not in shape or haven't worked out in awhile, you may get frustrated as this is VERY intense and may be beyond your ability at the moment. If you're looking for a challenge, then this is for you! I don't know about 20 pounds in 30 days, but I lost 5 pounds in a week just from doing this workout 3 times a week!

My mother and I just started this DVD and we love it. The first morning after I didnt think I felt much of a burn but when I started the next day WOW did I feel it. I am feeling it right now and I am still pumped to get to it again! I think the reason I love it so much is because I know that its working. When you are doing it you can just feel thats it working. It just makes me feel great!! Overstock had the best price out there so that helped too!!! Thanks Overstock!!

it's the perfect 20 minute workout. you can make it easier or harder by just changing the hand weights.

This workout DVD is incredible! I don't think it's quite fair that some people give it a poor review just because it's not their 'style'. I've been doing this workout for a week and a half (along with dieting) and no joke at all, I've already lost at least 2 inches from my waist. The workout doesn't necessarily get easier as you go along, it still works you out very well, it's just the fact that you have the endurance you didn't have when you first started. I tried level 2 and about died. She is amazing and I have no doubt that I will be able to see excellent results in no time! Going to purchase more of her DVD's!

These workouts seem to be very effective. Each work out - there are three sessions - gets progessively more difficult but since each one is about 20 mminutes they are very efficient. I personally enjoy the positive encouragement from Jillian. I can see myself buying more of her workouts in the future as I feel she is motivating which helps me keep my focus.

I have tried a lot of different workout fads and DVDs, and I do not care for Jillian at all. I'm a dancer and musician, so I like to do workouts that are set to the beat of the music, so that's a big reason why I don't like this workout much. The other thing that drives me crazy is that Jillian talks way too much. It's good for people who are new the working out and don't know how to do the moves with proper form. But for me, I know how to do a lunge and I want Jillian to suffer through the workout with me, not explain what the girl in the background is doing correctly. Overall, it's a decent workout, I just personally can't stand Jillian or this DVD.

I have only tried level 1 so far, but it is really challenging me and I consider myself fairly active. I am excited to move on to other levels as I progress. Only a mat and small hand weights are required/optional for working out with this video. I wish her intro speech could be skipped on the DVD to get right to the workout menu, so that is a creator flaw to deal with.

If you want a DVD that will kick your butt - this is the ONE! I really enjoy the 3 intensity level work outs. Each level is only 20-25 minutes, but feels like you've worked out for a full hour. Jillian Michaels gradullay works you into each level and you will get results. I never was a fan of Biggest Looser, but I am a fan of this DVD and am very pleased with my purchase. I have already recommended to a few friends to buy it and use it!
