A little jumping to help with your reaction time

An easy exercise to do to help with your reaction time (quickness) is a simple Hop Hop Hop Land exercise. Take a hip width stance. Be relaxed in your ankles, knees and hips. Stay neutral in pelvis/low back. Now jump just high enough so your whole foot leaves the ground 3 times, make sure you land with little or no sound at all. After the third "hop" land softy in a half squat. Repeat 5 to 10 times. You may use an arm swing if you like. This is a good exercise to reintroduce you to jumping if you've had to take time off due to an injury.
