Looking at this example is how i do it. Knees slightly bent. Pull to touch bar to abs, while retracting shoulders. short pause and release forward to full stretch.
But i dont keep my back that straight. I tend to lean back. I havent checked, but i guesstimate 30-40deg. Is that acceptable or should i focus on holding back at 90deg or near thereabouts?
