I just had an idea for a modified verion of a body lever that seem like it would be good for increasing ab strength for backwalkover and also increasing thoracic mobility.
Ok, so here is the regular version:

Now imagine that instead of stopping parallel with the floor the kid just kept going lower. You could further increase the the ROM by elevating the pad so that the feet had more room to fall. This would require a good amount of thoracic mobility.
What do you think? Could this be a decent assistance exercise for backwalkover? Has anyone already done this?
