If you want to be the fastest swimmer you can be, you'll have to work on your technique and mental attitude. Practice and perseverance are the key here. However, the most important thing is to master the technique well. Without the right technique there is no point in practicing. If you want to learn how to shave seconds or maybe even minutes off your best race times, read on to Step 1 to get started with lifeguard course near me.
Reduce the resistance you create. Swimmers often focus on swimming as fast as possible, not swimming with the least possible resistance. This is the resistance that your body encounters in the water. Remember that it takes skill and not strength to reduce this resistance. There are many ways to reduce your drag, such as improving your balance or swimming longer.  Never give up.
Improve your balance. This is a great way to reduce your resistance. To maintain balance, maintain as horizontal a position as possible as you glide through the water. This will minimize the amount of water in the way, which would otherwise slow you down. This is especially important when doing the freestyle, where you need to avoid lifting your head too much, something that upsets your balance, and having to kick harder to counterbalance.
This is a bit different from the breaststroke and the butterfly stroke, because your body makes an undulating movement instead of staying perfectly balanced during the swimming strokes.
Swim more expansively. Try to make yourself as tall as possible in the water. The taller you are, the better and faster you will swim. For example, if you want to swim more extended during the freestyle, you'll have to put the arm you're pulling back into the water sooner, once it's past your head; extend your coaxing arm forward as far as you can before starting the swing down and paddling it back.
Just think about this: if your body is all crouched instead of stretched out and long, it will be more difficult to slide through the water.
Make sure your leg stroke is as efficient as possible. When kicking with your legs, don't get above the surface of the water or move your legs too low below the line of your body -- again it's all about keeping the right balance. If you do not observe these rules, you will become unbalanced and create more resistance.
Improve your propulsion. This does not mean that you have to put in more force, but that you have to work on your technique. Remember that about 10% of the speed comes from your legs and the rest from your arms, so try to make those swimming strokes as neat as possible.
