Diuretic use: Medications used to treat high blood pressure or fluid buildup work in the kidney and flush excess fluid from the body, causing frequent urination. Prostate problems: An enlarged prostate can press against the urethra and block the flow of urine, causing the bladder wall to become irritated.
These fitness machines can read the chest straps and display the heart rate on the equipments' keypad. Either heart rate monitor is a more accurate than an exerciser manually taking his cardio pulse rate in the middle of exercise. Stage One: 60% to 70% of Maximum Heart Rate. Sometimes called the cardio fat burning zone, the first heart rate stage is between 60% and 70% of maximum heart rate.
Your resting heart rate should be between 60-100 beats per minute. If you are an athlete or train a lot, your resting heart rate could be lower. That is an average. Resting heart rate above 150 is tachycardia (fast).During exercise, you should shoot for between 40-60% of your heart rate max which is generally estimated by subtracting your age from 220.Example a 20 year old (220-20=200) would have a max heart rate of 200. You should be careful when starting exercise not to get your heart rate too close to max.For athletes-or people who often perform cardiovascular activity  - a normal resting heart rate may be closer to 40 beats a minute.      If your your heart rate is continuously above 120 bpm or below 40  bpm you should consult a doctor.
