I currently ask myself the same question. Any idea @beyondthewhiteboard ?
I`ve been asking this to, but no answer to date...
I've taken a firm stance with this one. I log the combined weight moved in one rep. A Single-Arm KB Snatch at 53# is the same weight moved for a (two-handed) KB Swing at 53#. Therefore, I record a Devil Press with two 35# dumbbells as 70#.
Also, it would be nice if someone at BTWBHQ would go through the movement database and clean out some of those ridiculous options and edit grammar and spelling.
