Rottefella NNN R3 Skate XC Binding
The Alpina NNN R3 Skate binding is a race-caliber binding designed to give you total control. Two grooves transmit power efficiently from boot to binding to ski, while notches in the grooves work to preserve the ski's natural flex pattern. Alpina's innovative dual flexor system stabilizes the ski, keeping the tip up and the length of the ski level during transitions. The wide 56mm platform offers further control, while an optional 3mm shim gives you the option to increase the binding height to a total of 8mm above the ski for maximum leverage during your kick.

Training Tips
After each interval, take your pulse rate by counting the number of beats at your wrist or neck for 15 seconds. Multiply that result by four to get your beats per minute. Your next interval should start before your heart rate is less than 60% of your maximum.
The four components of good fitness include flexibility, muscular endurance, muscular strength, and cardiorespiratory endurance. For optimum health, include at least two of these groups in three workouts per week.
Your fitness level will improve by overloading, working your body hard enough to stimulate the body, progression, increasing the frequency, intensity, and duration of exercise over time, and regularity, working out frequently, at least three times a week.
As your fitness improves over time by following a carefully planned fitness program, your ability to exercise closer to your maximum heart rate will improve.
