What is a good grip strengthener?
In Ask Cool Tools, I asked for a recommendation for a grip strengthener:
grip strengtheners. Some are lever-based and work all the fingers at once. Others are like a trumpet, with individual pegs for your fingers. Others are squishy balls/donuts. I’m mainly interested in improving forearm strength while I watch TV, listen to podcasts, etc. What do you recommend?
If you have a question of your own, please ask!
