Grip strength is essential for so many things -- particularly opening jars! With these hand & wrist exercisers, you can increase hand and wrist power the right way. Compact dumbbell weights are ideal for quick, efficient workouts. Take a pair of hand grips to the office for the perfect stress reliever. Other favorites include wrist rollers, massage balls and textured rings.
As a runner I can say that these are great for adding intensity to a workout. The ones I can carry and are easy to hold are particularly effective when your ability to run long or hard is limited -- in urban environments, for example.
