Do You Really Need a Creatine Supplement For Superior Physical Performance?

Creatine is something that you will hear a great deal about in any gym in the world. Bodybuilders found out some time ago that a good creatine supplement had numerous benefits for their bodybuilding endeavors. But in the grand scheme of things, can't you get the body that you desire without the use of this supplement?

Creatine is, after all, usually only thought of as a performance enhancement supplement, meaning that it will enable you to do better during your workouts, but that it has few, if any, benefits beyond this. Research shows that this is a mistaken belief. Other people believe that because they eat plenty of red meat and fish, which has this compound in it naturally, that they don't need a creatine supplement. This is also a mistake.

First, it is true that it is a natural performance enhancer, but it enhances more than just your performance. It also enhances your body's performance, by increasing anaerobic performance when you are working out. This does allow you to workout longer and harder as well.

You see, muscles are comprised of four different biochemicals, which include fatty acids, glucose, ATP, and creatine phosphate. All of these are necessary in the exercise and strengthening of muscles, and all of these biochemicals work together. Unfortunately, there is only so much that these biochemicals can do, and if you want them to do more, you need a supplement, which provides more of those biochemicals in the muscles...particularly creatine.

As with most things, there are those who will tell you why you shouldn't take this supplement. They will claim that creatine causes muscle cramping. Unfortunately for them - and fortunately for you - science has proven that it has nothing to do with muscle cramps. Muscle cramps are caused by a lack of hydration and low electrolytes. Experts agree that you need to drink one glass of water for every serving of creatine that you have.

It is also important to note that your body can waste creatine. You see, the muscles store this compound as 'stored energy' and use it as they are called upon to do more than they could without those stores. But you must think of your muscles as a container. Any container can only hold so much of any substance or item. Containers are not 'bottomless' and neither are your muscles. So, the muscles can only store so much of this compound at any given time. Experts agree that 10 grams of creatine a day is all that is really needed in terms of creatine supplements, because the muscles cannot store more than this.

While creatine improves your muscles response to your workouts, there are certain substances that actually improve upon it as well. Research has shown that creatine taken with Ribose increases the ATP in muscle cells. You can find products that now contain creatine and Ribose, and results of those who take a creatine supplement that contains Ribose have been great.

Caffeine is also great for creatine. As you know, however, too much caffeine isn't good for you. Experts advise one cup of coffee prior to a workout, which contains about 250mg of caffeine. You may need to experiment with caffeine with your creatine supplement, because everyone seems to have different reactions to caffeine.

Tennis Footwork - If You Really Want To Improve Your Game Leave Your Racket In Your Bag

This may seem like the most bizarre piece of information you've ever heard, but let's just back things up a little bit.

Let's think about what happens when you playing a game.

You get yourself into the point with a great return off a good wide serve by your opponent. You are moving (each other) all over the court building the point nicely when all of a sudden your opponent attacks by deciding to come to the net. You attempt a pass which they volley into the opposite corner and you head off to play a stunning running single-handed backhand pass down the line that a certain Mr Federer would be proud of.

Let's think about what just happened there.

You may have hit the ball maybe 6 or 7 times but what did you do for the majority of the point?

MOVE!

You moved to all of your tennis shots and you moved to recover.

The fact remains that the time spent hitting shots, never mind the actual time the ball spends on the strings is only a tiny fraction of the time spent moving to and away from your shots.

If this is the case, why do people spend so little time working on their tennis footwork and movement if it is the one thing you spend the most time doing?

FACT! The ATP tour stats on unforced errors are that over 70% of them are down to poor footwork.

Which means......?

If you really want to improve your game, it's very simple - you need to improve your movement and therefore your footwork.

And here is what you need to do!

When we look at footwork in tennis, the first thing you need to do is stop running so much on the court.

You should only run if you are a long way from the ball and it is the only way to get there quickly. Apart from that most of your movements around the court should be made using side shuffles and cross over steps (basically short step movements).

By having good footwork you get the flexibility of choice. You get to choose open or closed stance, cross court or down the line, backhand or inside out forehand, deep or short, passing shot or lob to name but a few. Without it you will have fewer choices available and the choices you do have may well suffer from poor execution.

You improve your agility, balance and co-ordination which are all vital components for high level play.

The type of footwork drills you should be using include cone drills like zig zags and drills that use ladders as a training aid.

My recommendation is that you start incorporating footwork drills into every one of your lesson/practice times. If your coach is not up to speed with all of this then do it on your own or find another coach!

You know that saying - what came first the chicken or the egg?

Well in the case of tennis it is without doubt the movement before the shot ' so try leaving your racket in the bag, work on your footwork and movement and discover how well you hit the ball when you finally do pull your racket out.

I have put together a special report on tennis footwork which goes into a bit more detail and includes 10 pages of drills to be used.
