Oblique Crunch Version 2

Body Part: Waist

Muscle: Obliques

Equipment: Body Weight

Oblique Crunch Version 2 is a supported side-crunch variation that puts the obliques in charge while the bench takes balance demands out of the equation. With the feet elevated and the torso free to move, each rep should feel like a tight curl through the side waist rather than a big sit-up or a hip-driven leg lift.

The movement is useful when you want direct work for the external obliques with help from the rectus abdominis, deep core, and stabilizers around the ribs and pelvis. Because the lower body is anchored on the bench, the setup lets you focus on shortening one side of the trunk and controlling the return without having to fight for foot placement or spinal position.

Setup matters more here than people expect. Lie close enough to the bench that your calves or heels can rest comfortably on it with the knees bent, then keep the ribs down and the neck long before you start the first rep. The working hand should support the head lightly, not yank it forward, and the opposite arm should stay relaxed on the floor for balance.

As you crunch, think about bringing the ribcage toward the hip on the working side and lifting only as high as you can while keeping the motion smooth. The goal is a clean side-bend with a small rotation through the torso, not a violent twist or a shove from the legs. A brief pause at the top helps you feel the side waist doing the work before you lower under control.

Oblique Crunch Version 2 fits well in a core block, as accessory work after compound lifts, or in a warm-up when you want to wake up the trunk without loading the spine heavily. It is beginner-friendly because the exercise is bodyweight and supported, but it still rewards careful execution. Keep the range honest, breathe on every rep, and stop the set if the neck, hips, or momentum start taking over.

If you want to progress the movement, slow the lowering phase before you add any outside load. A longer pause at the top or a slightly higher rep target will usually improve the quality of the set more than forcing extra range, especially if the goal is cleaner trunk control rather than explosive speed.

Instructions

• Lie on your back beside a flat bench and place your calves or heels on the pad with your knees bent roughly 90 degrees.
• Set the hand on the working side lightly behind your head and extend the other arm along the floor for balance.
• Keep your lower back close to the floor, your ribs stacked, and your chin slightly tucked before each rep starts.
• Let the shoulder on the working side rest close to the floor so you begin from a long, controlled side-body position.
• Exhale and curl your ribcage toward the hip on the working side, lifting the shoulder blade off the floor.
• Keep the elbow wide and let the side waist shorten instead of pulling hard on your neck.
• Pause briefly at the top when the oblique is fully contracted and the torso is still stable.
• Lower yourself slowly until the shoulder blade returns close to the floor, then reset before the next repetition.
• Finish the set by lowering your head and arm to the floor before removing your feet from the bench.

Tips & Tricks

• Keep the supporting hand light behind the head; if you feel pressure in the neck, you are probably pulling too hard.
• The bench is there to support the legs, not to help you drive the rep, so keep the feet quiet and relaxed.
• Think about shortening the side waist, not crunching the chest toward the thighs.
• A small range is enough if the shoulder blade clears the floor and the oblique stays under tension.
• Exhale as the ribs close and inhale as you lower to keep the rep smooth.
• If the hips start rocking, reduce the range and slow the lowering phase.
• Keep the elbow open instead of folding it toward your face; that helps the torso do the work.
• Use a deliberate pause at the top to remove momentum and make each rep count.
• Stop the set when the movement turns into a swing or the lower body starts pushing the bench.

Frequently Asked Questions

What muscles does Oblique Crunch Version 2 work most?

It mainly targets the external obliques, with the rectus abdominis and deep core helping to control the curl and the return.

Do my feet stay on the bench the whole time?

Yes. Keep the calves or heels supported on the bench so the legs stay quiet and the torso can handle the work.

Should I twist or just crunch sideways?

Think of it as a side crunch with a small torso roll, not a big twist. The ribcage should travel toward the hip on the working side.

How high should I lift on Oblique Crunch Version 2?

Lift only until the shoulder blade comes off the floor and the side waist fully shortens. A short, controlled rep is better than a high, sloppy one.

Why is one arm on the floor?

The bottom arm gives you balance and helps keep the torso from rolling too far while the top side does the crunching.

Can beginners do this exercise?

Yes. The bench support makes it a good beginner option as long as the neck stays relaxed and the movement stays small and controlled.

What if I feel this more in my neck than my side waist?

Lighten the hand behind your head and keep the chin slightly tucked. If needed, shorten the range until the oblique does the work again.

How can I make Oblique Crunch Version 2 harder?

Use a slower lowering phase, hold the top squeeze longer, or add reps before you add any external load or speed.
