Simple stress ball exercises can help minimize the chance of injury, promote flexibility, and build strength in your wrist, hand, and finger muscles. It can also aid with everyday duties, athletic performance, and hand and finger rehabilitation. The best part is that you don't need any special equipment to perform these exercises. You can use a standard ball of some sort - a tennis ball, a bouncy ball, even a medicine ball - so just pick one up at a local store. They come in many sizes and shapes, so there's one out there for everyone. Once you have your ball, start by doing simple stretches to warm up your hands and fingers. This will help prevent injuries from happening in the first place. After the warm-up, put the ball under your arm or next to your side and use both hands to roll it along the ground or across a surface, like a table or desk. Do this back and forth for five minutes per hand, then switch sides and repeat for the other five. This exercise helps build muscle mass in your wrists and hands which in turn increases their strength. Over time, you will find it easier to roll the ball without using your arms, which is when the real fun begins!
