How ABXCORE works
ABXCORE guides your torso through a controlled range of motion with adjustable resistance springs.
Instead of relying on momentum or neck pull, the movement keeps tension on your core so you can train with clearer form.
The system is designed to engage the rectus abdominis, obliques, and deep stabilizers—including the transverse abdominis—in one guided pattern.
Positions and arm setup let you emphasize upper abs, lower abs, or obliques without changing machines.
USC EMG research on ABXCORE measured higher core muscle activation than traditional crunches and ab-roller style movement under the study conditions.

How to set up ABXCORE
- Place the center brace on a stable floor surface with enough clear space around you.
- Slide both arms into the center brace with the spring windows facing outward.
- Attach your resistance springs securely before you sit or lie into position.
- Adjust width and height so the pads support you without forcing your shoulders or neck forward.
- Start in Seated Control if you are new—full support, slower tempo, focus on form.
Setup is meant to be quick. Use the video on this page as a visual check, then confirm the springs are seated before your first rep.
Choose your resistance
Every ABXCORE includes medium resistance springs (5 lb each, set of 4). Optional packs let you change intensity without changing the movement pattern:
Choose the lightest option that still lets you move with control through the full guided range. If form breaks, drop resistance before adding volume.
Your first ABXCORE routine
Keep the first sessions short and technical. The goal is clean setup, steady breathing, and feeling the work in your core—not racing through reps.
- Assemble the unit and confirm spring attachment.
- Use Seated Control with medium springs (or 3 lb springs if you prefer a lighter start).
- Move slowly through the guided range; exhale as you compress, inhale as you return.
- Stop while form is still solid. Rest, then repeat for a second short set if you feel ready.

Four-week beginner progression
- Week 1 — Setup & form. Short sessions. Prioritize seating, spring security, and smooth tempo.
- Week 2 — Consistency. Aim for a few sessions each week at the same resistance. Keep the range controlled.
- Week 3 — Position variety. When Seated Control feels stable, try Floor Control for more engagement with the same control cues.
- Week 4 — Progress with intent. Stay on medium springs if form is still improving, or move to 7 lb springs only if every rep stays clean.
Progress resistance or position only when your neck stays relaxed and your core—not your hip flexors or momentum—drives the movement.
- Pulling with the neck. Keep your gaze neutral and let the pads and guided path support the motion.
- Rushing the return. Control both directions; the eccentric phase matters.
- Starting too heavy. If you cannot complete a smooth range, switch to 3 lb springs or fewer quality reps.
- Skipping width/height fit. A poor fit pushes work into shoulders and hips instead of the core.
- Chasing fatigue over form. End the set when control fades.
ABXCORE is built for controlled core training. It is not a medical device and does not prevent or treat pain or injury.
If you have an existing condition, check with a qualified professional before starting.
Care and storage
- Wipe pads and contact surfaces after use so sweat does not sit on the foam and frame.
- Store springs attached or together so pairs stay matched for your next session.
- Keep the unit in a dry place—under a bed, in a closet, or against a wall is enough; it is built to stay compact.
- Inspect springs and attachment points periodically; replacement parts are available on abxcore.com.
