after finding your maximum heart rate, remember your target heart rate zone is 70-85% of your maximum heart rare, what would br your lower range ir your target heart zone?

To find the lower range of your target heart rate zone, you need to calculate 70% of your maximum heart rate.

Lower range = 70% * maximum heart rate

To find the upper limit of your target heart rate zone, you need to calculate 85% of your maximum heart rate.

Upper limit = 85% * maximum heart rate

Since the maximum heart rate is 100 beats per minute (bpm), the calculations would be as follows:

Lower range = 0.7 * 100 = 70 bpm
Upper limit = 0.85 * 100 = 85 bpm

Therefore, the lower range of your target heart rate zone would be 70 bpm, and the upper limit would be 85 bpm.
