I had an epiphany last night and wanted to make sure what suddenly seemed obvious is also correct.
During Single Arm Plank, I shifted weight into the supporting hand/shoulder slowly as I would when preparing to do a shoulder tap in handstand. I don't think the technique video mentions any specific intent to shift weight, but it made my single-arm plank so much more solid and with little to no tipping of the torso (that I felt... still need to do a video to double check).
So my question is, should I be shifting like that, or can I, as long as my torso remains level and the shoulder protracted?
Thanks,
Jennifer
