The Velocity Golf Fitness Program was scientifically designed to improve a golfer's:
1. Club head speed and power
2. Flexibility and range of motion
3. Posture, balance and alignment
4. Core stability and functional strength
5. Consistency and endurance
6. Overall fitness; which leads to a reduced risk of injury

VITAMIN E - YES OR NO?
A recent study showed that high doses of vitamin E do not decrease the risk of early death and may even slightly increase it. HOWEVER, this study did not distinguish between the different forms of vitamin E. Most vitamin E supplements are synthetic and derived from petroleum. The natural form of vitamin E comes mainly from soybean oil and is better absorbed by the body. The key components of vitamin E are called tocopherols. Reading the label will help you determine whether the supplement is synthetic or natural because the word "synthetic" is never placed on the label.

Look at the ingredients and you will see "dl-alpha- tocopherol." The "dl" in front of the "alpha" means that the vitamin E in the bottle is synthetically derived. The "alpha-tocopherol" refers to one of more than eight form of vitamin E found in plants. Most supplements, whether synthetic or natural, contain only the alpha tocopherol form. Some supplements contain the "gamma" form, which some studies suggest may have certain disease-fighting properties that that alpha does not. The best advice is still to get vitamin E through foods such as nuts, vegetable oils, whole grains, and leafy green vegetables. If you take a supplement, stick to the natural forms that have "mixed" tocopherols in an amount no greater than 400IU per day.

THE FACT BURNING ZONE
Do you burn more fat during a short duration, high intensity run or a long day of hiking? Are you in the coveted "fat burning zone" when you exercise or are you in the "cardio zone?" FACT: The intensity at which you exercise makes no difference as long as you burn more calories than you consume. What is important is the number of calories burned during the time you exercise. So, in a given time period you will burn more calories if you exercise at a higher intensity (cardio zone) than at a lower intensity (fat burning zone). Thus, if you exercise at a lower intensity you will have to exercise for a longer period of time.

Our bodies use different energy sources (fat, carbohydrates, glycogen) at different levels of exertion. "When you're working harder, explains Karyn Esser, associate professor in the Department of Physiology at the University of Kentucky in Lexington, your body burns a mix of fuel that's higher in carbohydrate and glycogen and lower in fat. At lower levels of exertion, your body mainly draws on fat stores to feet itself." Even when you are exercising at high levels of intensity you are still burning fat. You are also burning fat during the rest of the day as you recover from the high intensity exercise. The bottom line is always the same - burn more calories than you take in to lose weight!
