Place a couple of blocks or telephone books on a chair. Stand in front of the chair and elongate the spine keeping the posture in neutral. Try not to arch the lower back. Move into a sit position by bringing the buttock back and down and raise the arms forward into flexion at the same time. Then return to the standing position. Repeat for 3 sets 15 repetitions. When doing this exercise keep the knees over the ankles as well as in alignment with the second toes as much as possible. This stand-to-sit exercise is great for retraining the function strength of the lower quadrants if you have hip arthritis or have had a partial or total hip replacement surgery.
