The core is your foundation. It is the base upon which the other muscles are built. The muscles of the core consist of the abdominal muscles, hip flexors, lower spinal muscles and glutes (gluteus maximus and minimus). A weak core affects most motions done in hockey. Working on your core will improve your game and make your workout safer for the rest of your muscles.
One of the best programs for core exercises involves the exercise ball. Exercise balls are the large blow-up balls you can buy at most fitness, sporting goods, or department stores (like Target or Wal-Mart). They usually come with DVDs that contain instructions for a good core workout routine. Pilates is also a good way to work the core muscles. Abdominal crunches and pushups also are great alternatives.
By adding core strengthening to your exercise routine, you will improve the ability to balance, skate, shot and stick handle. Furthermore, your back and abdominal muscles will feel better when you need to really push your abilities. News reports have described an increase in injuries in high-caliber athletes over the last few years. By adding core work along with gentle stretching and strengthening complementary muscles, one can correct the imbalances in the body, improve function, and reduce the risk of serious sport-career ending injuries.
