The CoreTech Rebound Ab Trainer™ is built to make home core training feel more stable, supported, and controlled.
◆ Assisted Rebound System
A calibrated spring stores tension as you roll forward and provides supportive assistance during the return.
You still control the rollout distance, pace, and full movement.
◆ Stable Dual-Wheel Platform
The dual-wheel platform creates a steadier base and helps the trainer track smoothly throughout each rollout.
◆ Ergonomic Elbow Support
Padded elbow rests create a more supported upper-body position than a wrist-only grip, helping you stay focused on controlled movement.
◆ Built-In Workout Timer
Track your workout time while the integrated phone holder keeps your phone within view during your session.
◆ You Control the Range
Start with a short rollout you can control. As your strength and control improve, gradually increase your rollout distance or repetitions.
◆ Muscles Engaged
With proper technique, controlled rollouts primarily engage the rectus abdominis, transverse abdominis, and internal and external obliques.
The shoulders, lats, chest, arms, hips, glutes, and lower back also help stabilize the body throughout the movement. Muscle activation varies with rollout distance, technique, and individual ability.

Built-in digital workout timer (CoreTech Black or CoreTech White. Timer color may vary based on available inventory. Functionality is identical.)

Start with a shorter rollout that feels manageable and keep each repetition controlled.
As your control improves, gradually increase your rollout distance or repetitions at a pace that fits your routine.
CoreTech uses a calibrated spring mechanism that builds tension as you roll forward and provides supportive assistance during the return.
It helps guide the trainer back toward the starting position without pulling you backward or completing the repetition for you. You remain in control of the distance, pace, and intensity.
Place the included knee pad on a clean, level surface. Center your elbows on both support pads, hold both handles, and begin with a short rollout range. Keep your torso braced and stop before your hips drop or lower back arches. Increase your range or repetitions gradually as your control improves.
No. The Assisted Rebound System changes how the return feels, not who performs the repetition.
You still control the rollout, stabilize the trainer, brace your core, and complete every repetition. Begin with a range you can control, then increase your range or repetitions as your control improves.
The CoreTech trainer features a 100 mm main wheel, two 12.5 × 10 cm elbow support pads, a built-in digital timer, an integrated phone holder, and a stable dual-wheel platform.
Your order includes the CoreTech Rebound Ab Trainer™, integrated workout timer and phone holder, ergonomic support pads, and a knee pad. The timer and phone holder are built into the trainer. A phone is not included.
