Rubber Glove is a test for determining your Functional Threshold Performance (FTP). You will need a power meter (or a power-enabled trainer like the KICKR) or a heart rate monitor. This iMobileIntervals workout is optimized for use with the KICKR trainer.
At the end of the 20 minute interval the app will calculate your ftp and prompt you to save it to your account and settings. NOTE: if you clone and edit this workout, this feature will not be present! You will need to calculate the FTP as follows:
Assuming iMobileIntervals has been sensing power and/or heart rate, upload the completed workout to iMobileIntervals, TrainingPeaks or Garmin Connect and examine the 20 minute interval. Your FTP watts is 95% of the average watts for the interval. Your FTP heart rate is 99% of the average for the interval.
Enter your FTP values in your iMobileIntervals website user account or in the app settings so that the app can show you your target watts/hr and control the KICKR in ERG mode for the many workouts (such as TheSufferFest) that specify ERG as percent of FTP.
