Help a girl out!

A long time ago I did a work out and there was this one exercise that I loved! I wasn't part of this community so I can not find it in my calendar

It was with Daniel and Kelly, I believe it was a 5 day challenge but can not find it there.

The excersice was a push up from the back. I felt it so nice in my shoulders!

I want to this work out again so if someone is thinking I know that one please let me know!!

Thanx allot!
