Asuna 獨立式雙輪腹肌滾輪

I was worried about wobbling since I'm new to ab rollers, but the two parallel wheels keep it surprisingly stable. The grip handles feel solid and it's compact enough to stash under the couch. My core is sore in the best way after a week.

The parallel wheels really do make the movement steadier than a single-roller setup, and it's compact enough to stash under my couch. Took a few sessions to find my rhythm, but my core feels more engaged now.
