My hubby has a hard jump he is constantly picking up thousands of cases a day. This can really take a toll on the body, so to keep him in shape and to keep his muscles from feeling sore he takes protein shakes. Some people know them as a muscle builder. He takes the shake before he goes to work and after he comes home from work. It has really helped him keep in shape and help his muscles from feeling too sore and it has actually also helped him from losing muscle mass. They are not that expensive and you can buy them at Wal-mart for about 13.00 for a tub. They also have protein bars that are just as good as the shakes, so if you don’t like the taste of the shake you may like the taste of the bar as well.
