Head Skis USA Lightning i.M Super RailFlex Alpine Ski

The Head Lightning i.M Super RailFlex alpine ski is the ultimate ski for women looking for precise performance on piste and off. Why waste precious ski time deciding which skis to throw on the roof rack in the morning? The Lightning eliminates the need for a quiver. If you venture into the bumps or off-piste, these star-studded numbers will perform just as well as they do on hardpack and fresh corduroy. A hefty sidecut lets you roll the Lightning over and rail it through mammoth carved turns, or shorten up the swing and lay down some springy slalom turns through the chop. The RailFlex binding mounting system keeps the Lightning flexible in soft snow but absolutely stable on ice. The RailFlex system allows the ski to bend naturally, eliminating dead spots, enlarging the sweet spot. How sweet it is. *Bindings Sold Separately; SLD 11 RailFlex, LD 12 RailFlex.

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.
