    My Bowflex Series 3 treadmill suddenly won't give me a correct heart rate. Whenever I try to read my heart rate it comes up as 213 or 214 when I know it should be around 100 - 140. What causes this . . . and how do I fix it?

I will have to check the error code but sounds like a heat problem. When you get too much friction between the walk belt and the deck it builds a lot of heat which creates more drag on the motor. This causes the motor to overheat which in turn usually shuts the machine off. You can let it cool and go back exercising until the cycle repeats. If this sounds like your issue, try lubricating the walking belt. If it's not in bad shape it should make a difference. The machine should run longer. 10-15 is pretty quick though so it make take a couple of application of lubricant. The belt may need replacing if the need for lubricant becomes too regular.
