A couple of questions about Max HR & Target Aerobic HR. I'm 64 years old. Male ,5 ft 10 in tall. There's no history of heart disease in my family. I never smoked & have always been active, but over weight. (Black Belt in Judo & Scuba Diving instructor for 25 years) My weight has crept up about 1 lb/year since I got married 41 years ago. (age 23). Last summer I decided since I'm retiring soon, it's time to get serious, so I joined a gym. I work out 5 days a week, & occasionally my wife & I go on weekends as well. For the past 6 months I've used 220-60=160 Max HR & 135 (160 x 0.85) Target HR. I have dropped from 258 lbs to 221 lbs, since last August. I now weight less than I weighed when I got married (225). I'm feeling great. (despite a right knee replacement & arthritis in my left hip) The weight loss stalled last month, to just 2.5 lbs in March. (1/2 normal 4-5 lb rate) I have increased the intensity of my work outs to try to get back on track. & my cardio HR is up (138-145 BPM) On Friday I do HIIT on elliptical in the last 13-15 minutes of 45 minute session. My heart rate peaks at 160. I feel no ill effects, I'm not dizzy or faint feeling, other than being out of breath at the end. I recover within 2-3 minutes in the cool down period. So the big question is how firm are these MAX & target numbers. Should I be concerned that I'm at my Max HR during my HIIT or that I', above the target rate for my age? Mike D
Attached is my workout extracted from my Fitbit. The Heart rates agree with those on the elliptical during the session. Time Heart Rate (BPM) 8 min 122 32 145 35 158 36.5 160 38 158 39.5 162 42 1660 43.5 161
Attached is Friday's (Apr 13) work out. Last 10 minutes of HIIT. I have highlighted my peak heart rate 161 BPM, at 41 minutes
