The weighted plate side-up squat is a lateral core exercise that primarily targets the obliques and the deep stabilizing muscles of the waist. Performed from a side-lying position on the floor while holding a weight plate, it challenges the obliques through a full lateral crunch motion — making it an effective weighted progression for building side-core strength and definition.

How to do the Weighted Plate Side-up Squat

  1. 1Lie on your side on the floor with your legs stacked and your body in a straight line from head to feet.
  2. 2Hold a weight plate against your chest or extend it overhead for greater resistance.
  3. 3Place your bottom arm along the floor for light balance support, or keep it across your body if holding the plate with both hands.
  4. 4Brace your core and press your hips firmly into the floor to anchor your lower body.
  5. 5Exhale and crunch laterally upward, lifting your torso off the floor by contracting your obliques — your upper body should rise toward your hips.
  6. 6Pause briefly at the top when you feel a strong oblique contraction.
  7. 7Inhale and lower your torso back to the floor with control, keeping tension on the obliques throughout the descent.
  8. 8Complete all reps on one side, then switch and repeat on the other side.

Form tips

  • Keep your hips stacked and perpendicular to the floor throughout the movement.
  • Lead the crunch with your ribs moving toward your hip, not by pulling your neck or shoulder up.
  • Use a plate weight that lets you complete each rep with full control; the eccentric (lowering) phase should be slow and deliberate.
  • If holding the plate overhead feels unstable, start with it held at your chest and progress once your lateral strength improves.

Common mistakes

  • Rolling the hips backward as you rise, which recruits the hip flexors and reduces oblique activation.
  • Using momentum to swing the torso up instead of contracting the obliques, which reduces effectiveness and can strain the lower back.
  • Pulling on the neck to initiate the crunch, placing unnecessary stress on the cervical spine.
  • Skipping the lower-controlled phase by dropping the torso back to the floor, which cuts the time under tension and limits muscle development.
  • Holding too heavy a plate before mastering the bodyweight version, which causes compensatory movements and poor form.

Frequently asked questions

What muscles does the weighted plate side-up squat work?

It primarily works the obliques (both internal and external) and the lateral stabilizers of the waist. The deeper core muscles also activate to stabilize the spine throughout the movement.

How is this exercise different from a regular side crunch?

A regular side crunch uses only bodyweight. The weighted plate side-up squat adds resistance via a weight plate, increasing the load on the obliques and allowing for progressive overload as you get stronger.

Where should I hold the weight plate — at my chest or overhead?

Holding it at the chest is the standard starting position. Moving the plate overhead lengthens the moment arm and significantly increases the difficulty, so progress to the overhead position once you have solid form with the chest-held variation.

How many sets and reps should I do?

For strength and hypertrophy, 3–4 sets of 10–15 reps per side works well. Choose a plate weight that makes the last 2–3 reps challenging while still allowing full range of motion.

Can I do this exercise if I have lower back pain?

Lateral crunch movements are generally lower-back-friendly compared to forward flexion exercises, but if you experience any pain you should stop and consult a healthcare professional before continuing. Always brace your core and move slowly to minimize spinal stress.
