Front Plank Open And Close
Front Plank Open And Close Exercise Description
Front Plank Open and Close is a forearm plank with dynamic foot movement that challenges core stability while the lower body moves. The trunk stays rigid as the feet “open” wider and “close” together, training anti‑extension and anti‑rotation control. Primary stabilizers include the rectus abdominis, external and internal obliques, and transverse abdominis. The gluteus maximus and quadriceps help maintain a neutral pelvis and straight knee line, while the serratus anterior and shoulder girdle stabilize through the forearms. Performed with small hops or controlled steps, this variation increases demand on lumbopelvic control without sacrificing spinal neutrality. It’s a body‑weight drill that reinforces proper plank alignment, breathing, and full‑body tension.

How To Do The Front Plank Open And Close Exercise
‘- Set up prone on forearms with elbows directly under shoulders; forearms parallel.
– Press the floor away to slightly protract the shoulder blades without shrugging.
– Extend legs, feet together on the balls of the feet; head, torso, and legs in one straight line; gaze down.
– Brace the trunk (ribs down), maintain a neutral spine, and gently tuck to neutral pelvis; squeeze glutes and engage quads.
– Keeping hips level and torso still, move both feet out to about hip‑ to shoulder‑width via a small hop or controlled alternating steps.
– Land softly on the balls of the feet; avoid letting the hips bounce, pike, or sag.
– Bring the feet back together under control; continue opening and closing while maintaining a quiet, stable torso.
– Breathe steadily throughout; avoid holding your breath or flaring the ribcage.
– End the movement if you lose neutral alignment or feel the low back starting to take over the effort.
Front Plank Open And Close Tips
‘- Set your elbows directly under your shoulders with forearms parallel before you start moving your feet.
– Actively press the floor away to slightly protract your shoulder blades while avoiding a shrug.
– Keep your head, torso, and legs in one straight line with your gaze down to maintain alignment.
– Brace your trunk with ribs down, keeping a neutral spine and gently tucking to a neutral pelvis.
– Squeeze your glutes and engage your quads to help keep the pelvis neutral and knees straight.
– As you move your feet out, keep your hips level and your torso as still as possible.
– Open the feet only to about hip‑ to shoulder‑width, using small hops or controlled alternating steps.
– Land softly on the balls of your feet and avoid letting the hips bounce, pike, or sag.
– Bring the feet back together under control and aim for a quiet, stable torso throughout.
– Breathe steadily without holding your breath or flaring your ribcage, and stop if you lose neutral alignment or feel the low back taking over.
Front Plank Open And Close Beginner Introduction
Front Plank Open and Close is a body‑weight plank variation that mixes a steady upper body with moving feet. The body is supported on the forearms in a straight line, while the legs step or lightly hop apart and back together. This shifting base challenges the core to stay strong and steady as the lower body moves, building the ability to resist arching or twisting through the midsection.
Because the trunk stays firm while the legs travel outward and inward, this drill places high demand on the abs and side abs, with extra help from the deep core. The glutes and front thighs contribute to steady hips and straight legs, while the chest and shoulders support the upper body through the forearms. The emphasis is on control, smooth rhythm, and stable breathing rather than big, explosive motion, offering a more dynamic take on a traditional forearm plank for those looking to test core stability in a moving position.
