Place your feet on an elevated surface roughly around shoulder height, such as a box or bench, and position your hands on the ground under your shoulders.
Extend your body into a straight line from shoulders to heels and brace your core.
Lift one leg off the elevation while keeping your hips level and your body rigid.
Hold briefly, then lower the leg back to the elevation and lift the other leg.
Continue alternating legs while maintaining a stable plank position.
Form tips
Keep your body aligned in a straight line from shoulders to the supporting foot.
Engage your core to prevent the hips from rotating or dropping.
Lift the leg only as high as you can while keeping your pelvis stable.
Push the ground away slightly to keep your shoulders active.
