Mini Ball?

So, I have rather small hands (child’s size). I am unable to grasp a mini ball one-handed because of this. Does anyone happen to have any alternatives? I used a 2-pound sand-filled toning ball for the single-handed moves today.

Interestingly, I am a classically-trained pianist.πŸ€·β€β™€οΈ

Thank you in advance. πŸ’œπŸ©·πŸ’œπŸ©·
