Four-Wheel Auto-Rebound Ab Roller

This is a four-wheel ab roller. Compared to single-wheel models, it offers a larger support area, rolls more stably, and is less likely to tip sideways. It features an auto-rebound function that provides assistance on the return pull, making it friendlier for beginners and those with weaker core strength. Suitable for fitness beginners who want to train their abs and reduce belly fat at home; using it with a kneeling position gives better results.
