kinda dumb cause u're armbar - no your shoulders can't go any further
not with this load when ur butt swings back
byt if u curl legs up say on roman chair and then start flexinng spine - yes that's mostly abs, meager load though
do an dragon flag with legs (knee and hip bent) folded over pelvis but don;t't roll - lift entire bottom setup up
with abs, lift and hold, u can do it! for few secs, u will do it longer with abs it will grow :d
