I'm not sure if I understand what you're saying.
I think we agree on the conclusion based on different justifications.
I'm curious, are you implying that planks would help someone who doesn't use a belt? If so, how?
Okay. I inferred it from the fact that you distinguish the benefit of planks towards belted vs beltless lifters. For which I still don't understand how.
That's an interesting bet, but I'm just trying to understand your position.I bet you either know the answer or can easily figure it yourself.
