Sigma Onyx Balance
If you are thinking about getting into an exercise program to improve your energy level or lose weight, do not do so until you have purchased a heart rate monitor. A heart rate monitor can make a training session more safe by alerting you when you are pushing yourself too hard, and can increase the rate at which you burn calories by making sure that you always stay within the zone at which your body loses weight most efficiently. The Sigma Onyx Balance is an entry level heart monitor with a special slim design made especially for women, and an innovative new control method that requires no buttons.
The Onyx Balance was released by Sigma at the same time as the Onyx Classic. Functionally, the two units are the same, but the Balance is designed for women, with a slimmer body and light blue coloring. The Balance features the same buttonless control method found in the Classic: the entire watch face is the button, and can be pressed down at the top, bottom, or both simultaneously. Anyone who has ever fumbled for a button on their heart rate monitor during a training session is guaranteed to love this creative new control method.

Upon turning the Balance on, you will be asked to input some basic vital data about yourself. This information is used to calculate your estimated maximum heart rate, which is then used to determine two target heart rate zones. The Fatburner Zone, 55-70% of the estimated maximum rate, is the zone that you should train in if you are a beginner or are exercising to lose weight. Serious athletes, meanwhile, will want to train in the Fitness Zone from time to time. This zone, 70-80% of your maximum heart rate, should be utilized to increase the total cardiovascular capacity of your body, raising your endurance level.
During workouts, the Balance will alert you when you are outside of the target zone that you have chosen, while also keeping track of your average heart rate and the total amount of calories burned while training. No historical data is saved by the Balance, however. The Sigma Onyx Easy is able to record your workout totals for one year and is priced similarly. However, the Easy does not have the button-free interface of the Balance.
The Sigma Onyx Balance comes with the fitness watch, heart rate monitoring chest strap, and a bicycle mount to use the unit during cycling sessions.
