Plank hip dips are one of the most effective dynamic core exercises for targeting your obliques, transverse abdominis, and lower back without placing strain on your wrists or neck. By adding controlled lateral rotation to a standard low forearm plank, this movement challenges your rotational core stability, strengthens the waistline, and supports pelvic alignment—essential for maintaining posture and protecting your spine through midlife and beyond.

Exercise Overview & Anatomy
- Primary Muscles Worked: Obliques (internal and external), transverse abdominis, rectus abdominis.
- Secondary Muscles Worked: Gluteus medius, lower back (erector spinae), serratus anterior, shoulders (deltoids).
- Equipment Needed: Exercise mat (bodyweight only).
- Movement Category: Rotational core stabilization / dynamic plank.
Step-by-Step Setup & Form
- Set the Foundation: Start in a forearm plank (low plank) position on your mat. Place your forearms parallel to each other, distributing your weight evenly across the entire surface of your forearms rather than driving all your weight directly into your elbow joints.
- Align the Body: Stack your shoulders directly over your forearms. Tuck your pelvis slightly to prevent your lower back from arching, and squeeze your glutes, thighs, and back. Your body should form a straight, unbroken line from shoulders to ankles.
- Set a Neutral Neck: Look at the floor about 1 to 2 feet in front of your hands. Avoid tucking your chin against your chest or straining your neck upward.
- Execute the Rotation: While keeping your shoulders square and stable over your forearms, rotate your torso and lower your right hip toward the mat in a smooth, controlled motion. You do not need to forcefully slam your hip into the floor; lower only as far as your mobility and shoulder stability allow.
- Return and Alternate: Engage your obliques to pull your hips back to the neutral low plank starting position, pause for a split second, and rotate to lower your left hip toward the floor. Continue alternating in a steady, rhythmic tempo.
Trainer Form Cues & Common Mistakes
- Watch for "Traveling Feet": As you rotate side to side, your toes and feet will naturally pivot and may drift slightly away from you. That is completely normal. Simply pause, step your feet back into position, and resume.
- Avoid the "Pike" or "Sag": Do not let your hips rise into the air like a tent to make the movement easier, and never allow your hips to sag toward the mat, which strains the lumbar spine.
- Distribute Upper-Body Weight: If your shoulders or elbows ache, press firmly down through your forearms and palms rather than dumping all your weight into the joint point of your elbows.
- Scale with Knee Hip Dips: If maintaining a full forearm plank feels too intense on your lower back, drop to your knees while maintaining a straight line from knees to shoulders, performing the hip rotation from a modified knee plank base.
