Barbell Sitting on Floor Oblique Twist

Sitting on the floor with a light bar across the upper back, turn the shoulders from side to side; the floor locks the hips harder than a bench does.

How to do it

Setup

Sitting tall on the floor, legs crossed or straight in front, a light bar resting across the upper back, hands wide on it.

Steps

Turn the bar slowly to one side as far as the spine turns easily.
Stop the turn, then come back through the middle.
Turn to the other side with the chest lifted.

Common mistakes

Letting the bar's momentum finish the turn: stop each twist short of the end of the range. Rounding the lower back on the floor: sit on a folded mat or cross the legs. Bar on the neck: it rests on the upper back.

Breathing

Exhale on each twist, inhale through the middle.
