In this practice we will encourage the lumbar area to lengthen, with opportunities to release tight hip flexors. Postures such as Child's pose, squatting and resting semi-supine are very beneficial to stabilize and balance the sacroiliac joints.  A block or folded blanket will be useful for under the heels in squatting.  If there are knee issues then the squatting section could be done from standing and sinking into a half squat.
