Question: Is this bar sturdy enough for a 14 year old gymnast?
Document: This has been a fantastic practice bar for my 8 year old gymnast. It arrived as scheduled with expedited shipping - all boxes came at once (despite comments from others regarding piece meal shipping problems). Assembly was fairly quick and easy - about 30 minutes from unpacking to full assembly. Bar seems very sturdy, but I have noticed that the floor braces lift a bit when my daughter does big casts, but nothing to the point of it being a danger. My daughter uses it primarily for conditioning.
The bar arrived, was a cinch to put together and WOW, we are so pleased with it ! It is sturdy, no wobbles and fits perfectly on our living room area rug. I would highly recommend this bar to anyone who has an aspiring gymnast. It is high enough and sturdy enough that she will be able to use it for many years to come.
I have an 8 year old ballerina and a four year old gymnast. This bar adjusts to the perfect height for my ballerina to do either ballet or gymnastics. My four year old thinks it is the best toy ever. TV has not turned on since this entered our home a week ago.
This bar is awesome, so sturdy, my 8 year old can kip easily with no chance of the bar moving at all. Easy to set up, easy to raise and lower the bar, and seems safer than others on the market. The bar was a little rough at first, and ruined her brand new leotard, but we sanded it a little bit and it's perfect now.
Fun for a young and smaller gymnast... I purchased for my smaller 7 year old's birthday. Think in hindsight it would be best for the 4-6 year olds. It is sturdy. She can practice her kip and mill circle HOWEVER... even at its highest setting, its still pretty low especially when you have adequate mats underneath and the finish of the wood is much more rough than what they have in the gym.
Awesome. My 8 year old who weighs 50 lbs can do her kip element, practice her mill circles and front hip circles, and many other drills with the bar remaining stable.
This product is very unstable, in fact I think it is useless and unsafe because I am a gymnast myself and there are a lot of bad bars but this is the worst. This is also a bar I would only recommend for toddlers and the maximum age would probably be 6 years old and under. When I first tried this bar it would not stop shaking so we had to put cement bags on each side of the bar.
I have two girls ages 6 and 9, and thgey love this bar! It is very useful to help them practice when the are not able to go to  the gym. I dont know how much longer my 9 year old will be able to use it safely, she is 70lbs and sometimes it wobbles when she uses it.
This product arrived in three boxes all at once and was set up in about 20 minutes. It does not need bracing to the floor and my 8 year old son does back hip circles on this bar and it doesn't even shift or rock. Excellent product! My kids love this bar and practicing their tricks. The bar does not come with the mat as it is pictured here, however. You will need to buy a mat if you don't already have one.
This bar is great quality. My 9 year old daughter loves it. She weighs about 50 lbs and is on team. She loves that it's adjustable. I'm not sure the weight limit, but it held me and I'm 130 lbs.This item ships in 3 packages. Only 2 arrived. I contacted Amazon and they couldn't tell me if the other box was on it's way. They said I could return it and reorder.
Answer: yes
