Pros: No tools needed for assembly, which is very easy. Fun, effective workout.
Cons: Video workouts do not offer modified levels within a single workout.
First, this is not your run-of-the-mill mini trampoline. I have owned a Bodyflex trampoline for 3 years and rarely got past 5 minutes on it before getting off. I just did not like the feel of it. I decided to try the Urban Rebounder because it is advertised as having larger and stronger springs than other brands. I felt the difference immediately. Jumping on this trampoline makes me feel light and springy. It is fun and sturdy, too (I weigh over 200 pounds-but not for long - :-D). I worked up quite a sweat following the included workouts. I definitely felt the burn in my calves and thighs, and effectively hit my target heart rate. I often have discomfort in my knees with other exercises. Using the rebounder feels great. No joint pain at all. I look forward to doing these workouts regularly.
I have read some reviews of users complaining about breast discomfort due to bouncing. It is no fault of the product. Simple jogging or jumping jacks would render the same complaint. As with any exercise that involves plyometrics (jumping) or rigorous movement, a good support bra is in order--or you may have to wear 2 bras or a snug lycra tank over a bra for compression and added support. I am a 42DD, so I know the importance of good support. ;-)
As for those who would say this is not a complete workout, I would beg to differ. The workout involves cardio, resistance (if you are bouncing correctly, you should feel the burn throughout your legs up to your core), core and upper body muscles are also being worked. One might add small handweights or get the accessory resistance bands for increased upper body resistance.
I am no stranger to exercise. I use a Bowflex, P90X, and a treadmill. This has been a very welcome and valuable addition to my home gym and adds all the advantages of a plyometric workout without the impact. If you are new to rebounding, take it at your own pace. If you are feeling joint pain, check your form--make sure you're not jumping too hard (or too soon--you may want to begin by bouncing while keeping your feet in contact with the mat). Your body may need time to acclimate to a new routine.
Those who commented on the happy smiling people in the videos--remember that they are certified rebound instructors. Most group fitness instructors I have encountered are perky and energetic (although Traci seems to have taken several caffeine shots before the workout - LOL). The workouts are good. The one recommendation I would give the producers is to have multiple levels represented in each workout so that users can see modified versions if they feel they can't keep up, or alternatively - want to intensify the workout.
The product comes assembled (except for the balance bar, which snaps together in a minute or two) and is easy to set up (especially when one follows the instructions). I plan to use it regularly, so I simply fold the legs down and lean it against the wall next to my treadmill. It would just as easily slide under a bed.
I am quite satisfied with this purchase.
