Static push ups

I am thinking of adding static push ups my routine.
I found this from sethigherstandards.com (instructions how to do static pushups ):

The technique is this: after stretching a bit, place your arms slightly wider than shoulder width apart, and lower yourself only 3 inches. Hold this pose. Do not go too far down. Your arms should be almost (but not at) their point of complete lock-out.

Day 128:

An easy day. I did 30 and was satisfied.
