My husband had purchased the perfect push up for me a while back and the boxed stayed in my garage for months. I posted a thread a while back about toning my arms and I was told to do push ups. Well, as a result of some wrist injuries as a child and being a typist for 5 years, push ups put a lot of strain on my wrist. To be honest using the perfect push up or dumbells is the only way I can do push ups and not feel such a strain. I have to admit for me do the perfect push up with the twist is more challenging than doing them on my dumbells. But, if a person doesn't have problems with their wrist then they wouldn't have a need for the product and would probably find it useless. But for me it works, taking that pressure off my wrist.
