I mentioned balls as an option to offer in addition to the blocks. But, if the blocks offer plenty of lateral movement, then there would be no need.

The blocks are slightly curved side-to-side, meaning the center line (toe to heel) is lower than the edges. That's why it's possible to tilt and get knees well off center to both sides (both knees on same side). Hope that helps.
