Many of you already know about swimming snorkels. If you don't, or don't know where to get one check out your favorite swim shop or try www.finisinc.com. Snorkels do a number of things for your workouts and racing if that's your thing as well. They also get you incredibly fit aerobically.
When you swim with a snorkel first thing to remember is to hold it in your mouth; do not grip it hard or you will end up with tight jaws and that's no fun. It is easy to hold onto this training aid without overdoing so.
When you order one also get a "cardio cap". This is a device that you can eventually slip over the opening thereby reducing the size of the breathing hole. Wait a while before you do this...always move in progressions. If you have never snorkeled begin with a few laps and work your way to perhaps a 1000 yards or so comfortably. That may take some time and we all have time!
We will offer a number of different drills soon but for today let's just do this much: see if you can swim freestyle with a steady six beat kick the entire lap. A common stroke fault is that when you breathe you drop your kick, or do a cross over kick. Either of these is usually a result of your legs compensating for your head rotation. Without getting too technical in this forum we'd suggest a lap of freestyle with a steady six beat kick and pay attention to when you breathe through the snorkel and see if your legs stop when you breathe.
Sooner than later we will have video clips on our site showing some of these drills. And of course, we can always do video analysis of your strokes should you so desire. Give this a try and let us know what you notice about the relationship of your breath to your kick. See you soon...at the pool!
