Question: how do you close the rebounder?
Document: Meaning that, there is an automatic rhythm when you jump on a rebounder, somewhat like dancing.In fact, on evenings when you don't feel like doing a full workout, you can just do some basic jumps for a few minutes before going to bed. You might find it relaxing, as I do.I never used the stabilizing bar, never came close to needing it.
I first purchased this rebounder through Walmart. I paid more and close over $30 for shipping to get it faster. I didn't get it in for quite a while and when I did, it was in an old box and clearly beaten up and used. I was so disappointed. I had to take it into a Walmart and 2 hours later was finally credited. I realized this was a good mini trampoline I just needed to find a place that was honest. Well, I found it.
I bought this trampoline a little over a year ago, and I was mostly satisfied with it. It was noisy, and it wasn't easy to open and close, but I didn't fold it very often, so that wasn't an issue.
The workouts are fun, but some of the instructors can be annoying and it makes my exercise time less enjoyable. Setting up the trampoline was easy, but I have yet to fold it up again. I can't get it to close, and didn't want to risk injury from it snapping shut. More of an inconvenience than anything else.
I've only had this for a day, but I am addicted already! I just jogged on it for 10 minutes today and time flew by. I enjoyed the workout and I worked up a sweat! It was very easy to assemble, and it feels very sturdy. The weight capacity is 300lbs and I'm pretty close to that. When I stepped on it I was terrified but once I got to jumping I felt totally comfortable.
Also the mat itself seemed stretchy or something. What I mean by this is when I bounced with both feet close together I really sunk into the mat which caused my feet to bend with it. What ended up happening to me is that I got sore feet (with or without shoes). It's also super squeaky & creaky.I ended up returning it & buying a Needak. Yeah the Needak costs more but it's not outrageously expensive.
I was very disappointed.This might be okay as a starter for people looking to see if they enjoy rebounding, but it's not built to last, esp. if you are close to 200 pounds or someone that likes to jump high. Consider Jumpstart, Needak, Cellerciser, or Bellicon. You're going to spend 3-4 times as much but you'll have a real piece of exercise equipment imo.I upped this from 1 to 2 stars. The second one we got has lasted better.
I was putting my trampoline away when it snapped closed and hit me in the face. The strength of the springs that make the trampoline fold in half caused it close with such force that it split my lip open and nearly knocked my front tooth out. After a trip to the emergency room to have 7 stitches in my lip on the outside and inside and being monitored by the dentist to make sure my tooth doesn't turn black and fall out....I highly recommend staying away from this product.
i am using the rebounder,  assembly was fine . Only complaint is, it is noisy  other than that it works............
I put down my wii fitness and I just do the rebounder now I Love It.
