>>6318231On-hand right now, he doesnt ab crunch very much but he can bend back a bit. He can move side to side a little but he has this mid-torso section to get his torso to rotate left or right.
I might take a shot at this later if I feel like it but the biggest restriction for me on this pose is the wrist joints need to be rotated to get the hands to display exactly like in the OP.
