BATTLE OF THE FREE RADICALS. Some antioxidants are produced by the body and some by plants, and so they can be derived from the diet. Their job is to combat free radicals â highly reactive molecules formed as a natural by-product of cellular activity.
Grip (tennis) In tennis, a grip is a way of holding the racquet in order to hit shots during a match. The three most commonly used conventional grips are: the Continental (or Chopper), the Eastern and the Western. Most players change grips during a match depending on what shot they are hitting.
A support grip typically involves holding something, such as the handle of a bucket, for a long time. This type of strength is epitomized by the Farmer's walk, where the bucket is filled with sand or water, and carried over a long distance. A great deal of muscular endurance is necessary to have a good carrying grip.
