Posture is a REVERSE PLANK! = cat engagement of your hips and ribs while pushing hips forward, but because of the vectore of gravity (leaning backwards), it should appear as a straight line from knees to shoulders.

Tip: keep head neutral to gravity or even look down. Do not lean back your neck unless you want neck tension!

Cue: tuck tailbone under as you press hips forward into your palms (= posterior pelvic tilt)

Cue: pull ribcage down (= do not allow back to arch even slightly!)

Cue: squeeze knees together (= this will take the pressure off your knees and add support from you deep frontal line kinetic chain that connects the inside of your hips to your pelvic floor)

Cue: exhale back inhale forward (= helps to engage six pack contraction)

Imagine you are a Viking!
