How can I practice my left hand?

So, work on building up strength in your left hand. You can do this by lifting weights, of course, but an easier and more practical way to do it is just to use it more often. Instead of using your right hand to do daily tasks like brushing your teeth, washing dishes, and making the bed, use your left hand.

Where is the left hand?

Left-hand describes the position of something when it is on the left side.
