I'm Stephen Taylor, cycling and triathlon coach and personal trainer. Today we're going to talk about how to correctly wear a bicycle helmet. The materials you will need for this activity include a bicycle helmet that is the correct size and a melon to put it on. I've been told by retailers that an inexpensive helmet protects your head just as well as an expensive helmet. The difference is the more expensive helmets have better air flow, and they're lighter and possibly more comfortable. The important thing is, definitely wear a helmet when you are cycling. Now, I'll put this helmet on and we'll demonstrate a couple of adjustments that help ensure that the helmet is fit correctly. Make sure that the front of the helmet comes down and covers nearly to your eyebrows. We don't want your forehead sticking out because that is an area that we want protected in the unfortunate incident of a crash. Next, we adjust the strap that goes under your chin. You want to clip the strap and then tighten any excess strap so that it fits reasonably snug. A good guideline is that you should be able to fit two fingers under the strap, but no extra. The final adjustment that we make is usually done in back. Usually there is a dial or a clip that you tighten down to make sure that the helmet fits snugly around the circumference of your melon. Sometimes you may need to adjust the attachment points of the straps or the pads that are inside the helmet to make it most comfortable and fit correctly. This may take a little trial and error. In conclusion, it is a very good idea to wear a bicycle helmet when you're cycling. When we were kids we didn't wear helmets, but it's a very nice piece of safety equipment. Hopefully you never need the helmet, but in case you do, you'll be glad you had one on.
