Take a sledgehammer and wrap an old sweater around it. This is your "shovelglove." Every week day morning, set a timer for 14 minutes. Use the shovelglove to perform shoveling, butter churning, and wood chopping motions until the timer goes off. Stop. Rest on weekends and holidays. Baffled? Intrigued? Charmed? Discuss here.
I like to pretend I am shoveling coal into a train's steam engine. This is quite similiar to "stoke the oven", but I "fill the shovel" very low on the floor - the key here is to keep the shovelglove low. Then I shovel the coal into the furnace opening around hip height.
I find this hits the abs like, well, a steam train
Fits perfectly with my original inspiration for "stoke the oven" (and for "shoveling," come to think of it). Looks like you've got a nice little scenario going.
My fault for the confusion, Jürgen. The image I had in mind was the furnace of a steam engine, but because I've never done anything of the kind, I think the phrase I chose was slightly off.
I'm going to add mention of your combined move to the stoke oven movement page:
