When i received these push up bars it was clear what the premium price was for. These are well build and not like the cheaper no-brand version you can find on eBay.
For me these are ideal, because when I do normal push ups my wrists hurt. This way I can have a much better posture and include push ups in the morning for a more balanced stretch & light exercise.
If you are thinking of buying these swivel push up bars, go for these Adidas ones. You will not regret spending a bit more, these are build to last.
