Weight lifting for Parkinsons

Hi, I had my first NHS physiotherapy appointment yesterday and the physio had me lifting my arm using various weights and he recommended that I bought the weights myself to practise at home. Apparently it is meant to improve tremor in the hand. I hadn’t heard of this before and just wondering if any members had any experience of this kind of therapy?
