No pain, no gain. Right? But what's missing here is another critical aspect of training: rest and recovery. Overtraining leads to injury, illness and diminished performance. The body can endure just so much continual physical stress before it begins to break down.
So how do you know when to train and when to rest? The answer is heart-rate variability which measures the time-gap between your heartbeats when you’re resting. The heart, in fact, speeds up when you inhale, and slows down when you exhale. The difference is known as heart-rate variability (HRV). A healthy, well rested body will produce a wider gap than a stressed out, overtrained body.
Most endurance athletes are familiar with heart-rate monitoring during training and racing. But measuring your heart-rate variability is something you do at home, usually right after you wake up. HRV is not unlike the morning ritual of taking your resting heart rate to determine fatigue, overtraining or approaching illness. But measuring and tracking heart rate variability presents a more precise picture of your overall health. A high reading combined with a normal resting pulse is good news-- you can train hard that day. A low reading means you should take it easy, providing you with a guilt-free rest day. And while your body is in recovery mode, your muscles are busy getting stronger. That's because:
HRV was solely used by a small group of world-class athletes and their coaches. It was time consuming and difficult to track. Until now. The ithlete is a smart, simple-to-use device that works with your heart-rate monitor chest strap and your iPhone or iPod touch. A special app and receiver displays a color-coded graph of your HRV as well as a train / train easy / rest recommendation. The test takes just 60 seconds to complete.
ithlete will change the way you train. This affordable biofeedback training tool will finally give you the competitive edge you've been looking for.
