What is Plank to side plank?

Plank to side plank is a dynamic bodyweight core exercise that transitions from a forearm plank into a rotated side plank. It targets the entire core - especially the rectus abdominis and obliques - and is rated Hard for experienced trainees.

How to Do Plank to side plank

  1. Start forearm plank: Set up in a forearm plank with elbows under shoulders, body straight from head to heels, and feet hip-width for a stable base.
  2. Brace your core: Engage your core and glutes, inhale deeply, and maintain a neutral spine to prevent sagging or piking before initiating the rotation.
  3. Shift and rotate: Shift weight onto one forearm, rotate your torso while lifting the opposite arm toward the ceiling, stacking shoulders and hips as much as possible.
  4. Extend top arm: Reach the top arm straight overhead, open the chest, keep hips elevated and aligned, and avoid letting the lower hip drop toward the floor.
  5. Hold and breathe: Hold the side plank for one to three controlled breaths, maintain full-body tension, then prepare to return to center deliberately.
  6. Return controlled: Slowly return to the forearm plank with control, reset alignment, then repeat the same movement to the opposite side for balanced reps.

Frequently Asked Questions

What are the main benefits of plank to side plank?

Plank to side plank builds core stability, strengthens obliques and rectus abdominis, and improves anti-rotation control. It also challenges shoulder and hip stability for better functional movement and balance.

What common mistakes should I avoid?

Avoid sagging hips, rotating too quickly, flaring the shoulder, and holding your breath. Maintain a neutral spine, move slowly, and breathe steadily to protect the lower back and shoulders.

How can I progress or regress this exercise?

Regress with knees-down plank-to-side-knee transitions or perform the movement on an elevated surface. Progress by increasing hold time, adding controlled hip dips, or introducing a slow single-arm plank to increase challenge.
