Combination lunge, spinal extension, and spinal rotation

This video shows a combination movement to stretch multiple lines through the front of the body. Quads, all hip flexors, abdominals, intercostals are all targeted, as is the diaphragm. It's a very active exercise, meaning you are strongly pulling yourself into spinal extension and rotation. Super effective!

An addendum to this video shows a variation where you rest on the elbow of the bottom arm – this is very effective if you seek to emphasise the thoracic rotation aspect of this position.
