Over at Gymnastic Bodies you can see a demonstration of Planche Dips.
An excellent exercise to build upper body pushing strength.
Progressions:
This movement may also be performed with a tuck, advanced tuck, ½ lay or lay in addition to the straddle planche position demonstrated in the video.
And before I get any comments on this, let me just say that people who claim that full ROM dips are bad for your shoulders are probably the same ones that do quarter squats on bosu balls.
It’s the other way around, bad shoulder -> gets you pain when doing dips.
