The North Face Boundary Acclimate Jacket - Boys
The North Face Boy's Boundary Acclimate Jacket behaves like three coats in one. A 200-weight fleece is zipped into the HyVent shell, creating a warm ski coat that keeps out the water but won't collect sweat. Both the shell and fleece work as coats on their own, in case of warm wet days or cold dry ones. This versatility makes the Boundary Acclimate one of the best values in kid's outerwear, bar none.

Training Tips
Heart monitors are useful for knowing when you are in the right zone for your training efforts. If you understand what your maximum heart rate is, you can set up your monitor to beep at you when you exceed the high or low range of your heart rate for the type of workout you are doing.
Cross training gives your body a chance to recover while still exercising. If yesterday has a hard run day up and down hills, then today's bicycle ride gives your aching knees a well deserved break.
Anaeroic threshold is when lactic acid starts to build up in your body as your muscles are not getting the oxygen they require. This threshold is typically expressed as a percentage of your VO2 max - the amount of oxygen per kilogram of weight that a person can use in converting fuel to energy. Elite athletes threshold might be as high as 90% of VO2 max.
Efficient running position allows you to run farther and faster. Keep the heel raise to a minimum, relax your upper body and hands, keep your upper body poised and quiet.
