How to Use a Bench for Abs: A Clear, Practical Guide

Yet, this simple tool can transform your ab workouts, helping you build a stronger, more stable core while protecting your lower back.

In this guide, you’ll learn how to use the ab bench properly, whether it’s at your local gym, at Planet Fitness, or with your own adjustable bench at home.

What Is an Ab Bench?

The abdominal bench, sometimes called a crunch bench or abs bench, is a padded bench set at a decline. It supports your back and hips while allowing you to perform controlled crunches, reverse crunches, and oblique twists. Unlike lying flat on the floor, using the abs bench increases your range of motion, engages your core more deeply, and helps maintain a safe posture.

How to Use an Ab Bench for Effective Core Work

1️⃣ Adjust the Bench

• If your ab bench is adjustable, set it to a decline that matches your fitness level. Beginners may start with a slight decline, while advanced users can handle steeper angles.

• Ensure the foot pads are secure so your legs stay stable during each rep.

2️⃣ Standard Crunch on the Ab Bench

1. Sit on the bench, hook your feet under the padded rollers.

2. Lie back with your lower back in contact with the pad.

3. Cross your arms over your chest or place your fingertips lightly behind your ears.

4. Exhale as you contract your abs, lifting your shoulders toward your knees.

5. Inhale as you lower back slowly with control.

3️⃣ Reverse Crunch on the Ab Bench

1. Lie back with your head near the top of the bench.

2. Hold the handles or the sides for stability.

3. Bend your knees and lift your hips toward your chest, engaging your lower abs.

4. Lower slowly, avoiding swinging.

4️⃣ Oblique Crunch for Side Abs

1. Perform the standard crunch, but as you lift, twist your torso to bring your right shoulder toward your left knee.

2. Alternate sides with each repetition.

Using the Abs Bench at Planet Fitness

Many ask specifically how to use the abs bench at Planet Fitness. Their abs bench typically has adjustable decline settings and stable foot rollers. Follow the same steps above, focusing on slow, controlled movements to avoid momentum-based swinging, which reduces effectiveness and increases the risk of strain.

If you feel unsure, ask a Planet Fitness trainer for a brief demo to check your form.

A Personal Note on Training with the Abs Bench

When I first added the abdominal bench to my routine, I was surprised at how different my abs felt compared to floor crunches. The extra range of motion challenged my core, while the stability helped reduce neck strain. Over time, I noticed not only better core definition but also improved posture and lower back support during other lifts like squats and deadlifts.

If you’re aiming for stronger abs or simply want to improve your core stability, don’t overlook the power of a properly used ab bench.

Tips for Success

✅ Start slow: Begin with 2–3 sets of 10–15 reps using bodyweight before adding weights.
✅ Avoid pulling on your neck: Keep your hands light behind your head if you choose that position.
✅ Breathe intentionally: Exhale on the effort, inhale on the way down.
✅ Combine with other core exercises: Add planks and hanging leg raises for a balanced routine.
