I've been doing these bastards and getting good workouts. It's funny the dude in the video learned them from Matt Furey... that's where I first came across them and been doing them ever since
I purchased his book. It has this and other good exercises in it.
But they should be called Yoga pushups, not Hindu pushups. But when a name sticks ...
Tey are tough to do with a shoulder injury (rotator cuff), but I used to do them well.
