Why train with a heart-rate monitor?
Finding your personal heart rate zone and training with heart rate intervals allows you to maximize your workout. Simply put, if you train at lower heart rates (BPM or Beats Per Minute) it will require you to workout longer to achieve benefits. If you work out at BPMs that are too high for a prolonged period, you will burn out too fast, before you’ve reached your workout goals. Rhythm24 has advanced optical sensors that will give you a precise BPM reading so you can stay in your zones and receive the maximum benefit from your workout!
The chart below illustrates the relationship between heart rate levels and workout efficiency during interval training. Please consult your physician before starting any exercise routine to ensure that you are healthy enough to engage in a training regiment. Heart rate zones vary by a person’s age, consider consulting a personal trainer regarding the appropriate heart rate zones for you.
* Maximum heart rate varies depending on your personal health and fitness level. Consult your doctor and trainer prior to heart rate interval training to determine your max BPM.
