The main point of stretching your fingers is to improve flexibility, relieve stress and avoid pain in your fingers. Stretching your fingers is especially important if you have a job where you spend a lot of time in front of a computer. This is a simple stretch exercise you can do in your car when driving to and home from work.
Place one finger on the steering-wheel and gently press down. Keep the tension for a desired amount of time before relaxing and moving on to the next finger. Work you way through your fingers one by one before switching hand. You can stretch your fingers both down and up for maximal efficiency.
Given you don’t experience any pain when preforming the exercise you will benefit from stretching your fingers several times per day.
