Of course there are different views on this:
The Perfect Pushup was designed by former Navy SEAL Alden Mills. Considered to be the toughest military training in the world, SEALs make use of the latest science and technology to prepare for the military's most challenging missions.
The Perfect Pushup's unique rotating handles allow your arms to rotate naturally during pushups, the same way they do when you throw a punch, or press up a dumb bell.
This unique rotational feature accelerates results by engaging more muscles in the chest, arms, shoulders, and back.
The Perfect Pushup reduces strain on wrists and elbows, while helping stabilize and strengthen the shoulder joint and rotator cuff muscles.
Mills carefully observed the PT during his SEAL training, and learned that exercises that follow the body's natural movement patterns help you:
• Reduce strain on joints and muscles
• Get stronger faster
• Minimize injuries
I have a small RC injury to my left shoulder...I was told by the therapist not to do any overhead weight training, especially bench presses and clean and jerks, which i was doing much of.
Any 'pushing' horizontally and pulling, such as in overhead pull downs and in rowing...is OK.
After using these rotating handles in pushups...my shoulder RC feels much better and my overall upper body explosive strenght seems to have increased.
