I do a sequence that takes about 10 or 15 minutes, but I sometimes do it twice.
It's basically a vinyasa flow sequence: mountain pose, standing stretch, tree pose on each leg, forward bend, table top, [plank, cobra, downward-facing dog, 3-legged dog, step through to runner's lunge, high lunge, warrior pose, peaceful warrior pose, triangle pose], then repeat from plank on other side. Plank, cobra, downward-facing dog, walk feet up, squat, cat-cow pose, cobbler's pose, finish in shivasana.
Sounds long to remember, but each pose flows quite naturally from the previous one.
