Spine lumbar twist stretch

Lying flat on your back, cross one leg over the other by twisting your hips and spine. Keep your opposite arm outstretched. You can hold on to your knee to make the stretch stronger if you feel comfortable.

It really helps to stretch my lower back each day.
Pain is easing.

This is good and helpful but should the foot be in front of or behind the other leg's knee as she changes this between each stretch?

Your back is not supposed to be straight on the floor right?

[brandychugger]

Should this hurt or cause uncomfortable popping??

Is it more important for the knee or back to be on the ground?
