This neat hand exerciser is great for any size hand. I tried it out and thought I was doing well until my husband changed the tension with the red knob on the front. He tightened it up so that I could barely move the lever. I would think you would want to start slowly in repetitions and work up to a harder pull to gradually strengthen your hand. I've a long way to go and this will help me with my joints and grip. As I age, my grip tends to get weaker and I'm more susceptible to things slipping out of my hand AND those prescription med bottle caps are harder to unscrew.
I received this product at a discount in exchange for my honest and unbiased review.
