Day 167 so far (diamond push ups)

I have done 30 regular push ups so far.
I also have done 19 (10+9) diamond push ups - I will consider getting some gloves since my hands were slipping.
10 diamond push ups in a row is currently my personal best.

Why the name Maltese push ups

I have not been able to find out why "Maltese push ups" are called just that.
Anyone who knows?
