Learn how to dive like a pro and rescue a drowner

Nothing's more refreshing than going for a summer dip or performing the perfect dive.  These important instructions will help you perfect your technique and equip you to help those in need.

A well-executed dive is by far the most graceful way to launch yourself into a pool, and it also generates momentum for your swimming stroke. Here's how to score a perfect 10:

• Stand with the toes of one leg (the one you kick with) at the pool's edge. Set your other foot slightly back from the edge. Link hands and straighten your arms above your head.
• Bend both knees slightly and allow yourself to tip forwards.
• As you strike the water, straighten your legs, keep your hands linked, your arms up, and your body in a straight line.
• As your downward momentum slows, steer your body up towards the surface, kicking your legs for added speed.

Most importantly, don't try to leap into the water and rescue someone unless you're a trained lifesaver. You could easily become a victim yourself. Follow these steps in someone appears to be drowning:

• Shout for help.
• Call for emergency services. You can also assign someone else to do it so that you don't take your eyes off of the victim.
• If there's a buoyancy aid - such as a lifesaver or other floating object - throw it. Look around for a lifebuoy on a line or tie a lifejacket to a rope.
• If there's no lifesaving equipment nearby, throw something like a tow rope as a lifeline. You can also reach out with a pole, oar, fishing rod, or tree branch.
• Don't go into the water unless you're trained in rescue. If you have to wade out, stay within your depth and ask someone onshore to hold a rope tied round your waist. Take a buoyancy aid for the person to hold onto.

If you've gotten the victim out of the water, follow these steps:

• Remove any mud or weeds from the nose and throat and perform CPR if needed.
• If vomiting or regurgitation occurs after you begin CPR, roll the victim on to their side to clear their airway.
• Treat for hypothermia.
• Keep trying to revive the victim until trained help arrives.

It's important to be prepared when going for a swim. Study these tips carefully and you'll be ready for anything, from helping someone in need to simply executing a graceful, flawless dive.
