I used this video for a week, and I saw results quickly. I lost 1/2" off of each thigh. I found this video to be incredibly challenging, and I loved that. Each day I felt myself getting stronger. I couldn't even make it through the first level when I started, but by day 7 I had no problems with endurance. Unfortunately, my knees were a different story.

I know the proper form for squats. I actually do a fair amount of powerlifting with a good number of heavy squats. I do it 2-3 times a week, and I've done it for almost 2 years. I trained with incredibly strong men with good form, so I know the importance of not letting the knee go over the toe during a squat. I could squat 155 lbs without knee pain, so I'm not convinced that this video is not hard on the joints, even with proper form. I also practiced ballet for a while, which is notorious for screwing with knees, and I never once had knee pain. After one week of this DVD, I began experiencing soreness in both of my knees, so I thought I would give it a few days off. It's been almost three weeks, and my knees are still incredibly sore and stiff. They snap and pop, and I'm not sure when they will get better. I've been using proper form for 2 years on exercises, so I'm not sure every person who experiences knee pain after this DVD is to blame for improper form.

I think this video can provide good results, but I encourage those who want to try it to use caution.

I did both this workout along with the metabolism boost dvd this week. I have no doubt these programs will burn calories and help you lose weight. However, my doctor (who is a marathoner and weight lifter) practically jumped down my throat when I told her that I did these programs b/c I have a history of knee injuries. These dvd's are for advanced exercisers. Try to build up knee and leg strength before trying these. I injured myself after doing too many jumping jacks (yes, she actually incorporates those) and jumping squats (you have to turn 180 degrees believe it or not). If you do not land in a stable position (and this is a big "if") you can seriously injure yourself. Hopefully I can lose some weight over the next few months and work my way to this, but for the time being I wanted to put out a "Buyer Beware" on this dvd....it's a fat blaster....but with a very high risk of injury. It's not worth injury if you ask me. Back to the FIRM...great results using cardio/weight interval combinations but no risky jumping moves.

be warned it is mostly high impact (lots of jumping jacks).. I've always been very active, fit, lean and 33 yrs old and this workout affected by knees.. for this reason, I don't think I will stick to it.

This is definitley a strenuous workout, but even the level 1 beginner routine is too intense for someone not already in shape. I hurt my knee almost immediately and then my back. I wouldn't recommend this to anyone with weak joints.

It takes way too long from when you put in the DVD until the work out starts. There must be 10 minutes of 'commercials' in the beginning! The DVD does not let you fast forward through them either. More marketing than work out. I bought a bunch of Michael's DVDs and if I could return them, I would.

There were areas I really liked about the program, especially the strength training and core exercises that I've incorporated into other areas of my fitness routine, but overall it was very hard on my joints, especially my knees, for which I'm still paying. I don't normally write reviews of products, but I felt I needed to for anyone out there that may have weak knees/joints so that they would think twice or at the very least take precautions (that I obviously didn't) before doing the program. I believe another reviewer mentioned modifications for knees (padding, especially during the modified push ups) which should be heeded. I hadn't done high impact exercise for a while and I should have thought twice before "jumping" right in. My knees and I will be doing low impact from now on.

I bought this after trying level 1 a few times On Demand. I guess i'm kind of a sheep because I thought, "if she's so popular, there must be something great about this" but really...no. the workout is hard, i'll give you that. my problem is that it doesn't give you enough of any one kind of workout to be really successful. it's not enough cardio that you can get away without doing anything else, and the same goes for strength training. also, jillian's approach to motivation is telling you to keep going even if it hurts, which is kind of idiotic. i'm not surprised there are so many complaints on here about knee problems, i had them myself!
although this is called, "30 day shred" i took 60 days to complete it (meaning i did each level 10 times taking off a day in between) but near the end i was so bored i would rather do anything else but this!
if you want a good strength workout invest in Pauline Nordin's "Butt Bible" She's pretty funny and gives you different workouts for upper and lower body so you can give your muscles time to rest!

I like the structure of the workout in this video, i.e., 3 minutes of strength, 2 minutes of cardio, and 1 minute of core. It is a very effective workout and pace, and makes the most of 20 minutes. However, I was really disappointed that there was no low-impact modification available for people who can't jump. I have always been a fit person, but I can't do high impact because I have had 2 knee surgeries. The video starts right off with jumping jacks, and my knees hurt immediately. Jillian says in the video that she will not give an alternative because she has seen 400 pound people do jumping jacks, so there are no excuses. There should always be modifications so people don't hurt themselves. I expected more than jumping jacks and "no excuses" from someone who is supposed to be a great trainer.

I am typically pretty careful about positions and was uncomfortable about two particular exercises...not feeling like It was quite doing it write, using windows to try to check my form. I was still doing yoga and am somewhat flexible, but was hoping for a good push toward some aerobics to get back into the groove after a winter hiatus. Summers I tend to workout for 1-2 hours per day, 5-days a week, so a tough short workout seemed like just what I needed.

I would not recommend for those who have been sedentary for for a few months and getting started again. I thought that is what Jillian's workouts were about.

This workout will definitely make a difference, but it is very hard on your knees. If you have chronic knee problems then I would suggest looking for something else. I have chrondomalacia which I keep under control with orthotics and care in my choice of exercise. Running is usually out for me, as are lunges. This workout was a big fat "no" for me. I only did one session and my knees were inflamed for a week.
