Plank Arm Lifts
Plank Arm Lifts Exercise Description
Plank arm lifts are a forearm-plank variation that challenges core stiffness while the arm moves, training the body to resist rotation and extension. The movement emphasizes the anterior core (rectus abdominis, transverse abdominis, and obliques) with help from the glutes and spinal erectors to maintain a neutral spine. The reaching arm trains shoulder and scapular stabilizers, including the deltoids, serratus anterior, trapezius, and rotator cuff, as you keep the torso steady. Expect a strong anti-rotation demand: the goal is to keep the pelvis and rib cage level while the arm lifts. This drill builds precise trunk control and shoulder stability useful for many upper- and lower-body tasks that require transferring force without trunk movement.

How To Do The Plank Arm Lifts Exercise
‘- Set up in a forearm plank: elbows stacked under shoulders, forearms parallel, legs straight, toes tucked.
– Align from head to heels in a neutral spine; gaze down, ribs gently down, pelvis level.
– Create tension: press the forearms into the floor (slight scapular protraction), brace the abdominal wall, and squeeze glutes and quads.
– Set feet hip- to shoulder-width to create a stable base without letting the low back arch.
– Without rotating or shifting, slowly lift one forearm and reach straight ahead to shoulder height, palm facing in/thumb up.
– Keep hips and shoulders square to the floor; breathe steadily—do not hold your breath.
– Pause briefly with control, then lower the arm to the original forearm position.
– Reset your brace and repeat on the other side, alternating arms while maintaining a level pelvis and quiet torso.
– Quality checks: avoid sagging or hiking hips, flaring ribs, or shrugging the shoulders toward the ears; move only as far as you can keep the trunk still.
Plank Arm Lifts Tips
‘- Stack elbows directly under shoulders with forearms parallel to start.
– Align head through heels in a straight line, keeping a neutral spine and gaze down.
– Gently draw ribs down and keep the pelvis level before lifting the arm.
– Press forearms into the floor with slight scapular protraction to help create full-body tension.
– Brace the abdominal wall and squeeze glutes and quads before and during each arm lift.
– Place feet hip- to shoulder-width to build a stable base without letting the low back arch.
– Lift the forearm slowly to shoulder height without rotating or shifting the torso, keeping hips and shoulders square to the floor.
– Breathe steadily throughout the movement and avoid holding your breath as the arm reaches.
– Only lift the arm as far as you can keep the trunk still, avoiding sagging or hiking hips, flaring ribs, or shrugging the shoulders.
Plank Arm Lifts Beginner Introduction
Plank arm lifts place the body in a low forearm plank while one arm reaches forward, turning a familiar position into a powerful stability challenge. As the arm moves, the rest of the body stays braced against tipping, twisting, or sagging, so the midsection works hard to hold a straight line from head to heels. This creates a demanding core exercise that blends balance, strength, and control in a single movement.
The front and sides of the abs take center stage, with strong help from the glutes and muscles along the spine to hold a steady posture. At the same time, the reaching arm trains the shoulders and upper back to support the joint and shoulder blade while the base shifts to one forearm. The result is an anti-rotation drill that hones full‑body tension and precise trunk control, useful any time the upper or lower body generates force while the middle of the body stays stable.
