Upside-down pendulum

A. Stand with feet wider than hip-width apart and knees slightly bent. Hold a 3- to 5-pound dumbbell between both hands, and extend your arms toward the ceiling.

B. With head between arms, bend to the left as far as possible, keeping hips and shoulders square. At the last moment, rotate toward floor, then rotate back to forward-facing position and return to arms overhead. Repeat on other side, moving smoothly (like a pendulum). Do 10 reps per side.
