2 sets, alternating left/right for a total repetitions each side.

Start on all fours with knees directly under hips and hands directly under shoulders. Keep back neutral or slightly arched and chin tucked.

Slightly brace abdominal muscles, lower back muscles, and pelvic floor muscles to lift and extend one arm and opposite leg. Do not allow upper body or hips to rotate. Slowly lower leg and arm back to floor and repeat with other leg and its opposite arm.
