Question

Quizplus · Accepted Answer

Step 1: 
Maximum Heart Rate (MHR) = 220 - Age
MHR = 220 - 25 = 195

Step 2: 
Heart Rate Reserve (HRR) = MHR - Resting HR
HRR = 195 - 75 = 120

Step 3: 
Target HR = (HRR x 0.85) + Resting HR
Target HR = (120 x 0.85) + 75
Target HR = 102 + 75
Target HR = 177 bpm

Therefore, the correct answer is C) 177 bpm
