LT Interval Method
Question: When doing LT intervals using heart rate as the indicator, how should one go about regulating the intensity for the duration of the interval? For instance, if one has determined their LT heart rate to be 175 and they are doing 10 min. intervals, should the goal be to reach a heart rate of 175 after 2 min. or after 6 min. (or whatever other point) and then hold for the remainder of the interval?
Your thoughts on the method for doing the interval would be greatly appreciated. I myself try and maintain the LT heart rate, ie. 175 bpm, for the last 3 min. of a 10 min. interval. So I would slowly build intensity over the first 7 min. to ensure that my HR is at 175 at the end of 7 min. Would you consider this to be too easy?
