This is 10 bucks but there was another one that rotates called “perfect pushup” which is more expensive.
These would only be advised if you must keep your wrist straight due to pain, etc.
The body actually functions better and more safely when pressing off the full palm. This includes the handstand pushup. If you're looking to increase range of motion (dropping chest/head below plane of hands), then just use some sturdy blocks/books/bricks.
As someone who does hundreds of push-ups daily, I would say there is no need for those. To get greater range of motion, use blocks, reams of paper with duct tape added to the wrapping to fortify em.
they are probably not going to do you much good as far as pushups go, but they would be helpful for other maneuvers:
this guy uses them for various things.
the rotating ones, i find are good just because they exercise other areas, but i wouldn't pay more than $10 for them and they certainly aren't necessary ... unless you want to be amused listening to 'sergeant' whats-his-name:
probably better to just do pushups instead of cluttering one's place up with gizmos. here's a large variety:
and this is neat:
and vegan frank medrano is even neater, imho:
I have the perfect push up ill give it to you if you want it i live in nyc i am about to give it away as i clear my closet
i think its better on the hand/wrist to do normal push ups
its another gimmick i bought into long ago
No need at all - but if you are concerned about your joints in your wrists, slowly conditioning yourself to do pushups on your fists and fingertips, with multiple variations (http://greatist.com/fitness/bodyweight-push-up-variations love this link!) will work wonders for your body and core strength if done a regular basis.
I can't say it's a bad pushup tool, but nothing particularly special about it, imo. Not necessary, but will exhibit a range of motion that's different than usual. Perhaps may be useful for a martial artist looking into more conditioning exercises that simulate the punch.
