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.
