Hi! I'm having difficulties figuring out my BFP. The Karada scans that I had are inconsistent (BFP = 25.2%, BMI = 21.4; then BFP = 27.2%, BMI = 20.9 just three days later), so I cannot rely on it anymore. I noticed that the lower my heart rate was at the time of testing, the higher my assessed BFP was, too. I understand that active people are supposed to have higher heart rates. Theoretically, my RHR of 45bpm (plus my dismal BFP) means I am a lazy coach potato.
The thing is, I exercise 6 times a week. I make about 8000-12000 steps, do light weight-training for 30mins, and light cardio for 30mins. My muscles, though certainly average, are relatively more prominent than most of my female peers. We even eat and sleep at almost the same amounts. Still, after we all did a three-minute step test, they have heart rates above 140 and I at 112. I am certain that I have more physical activity than them (case in point: after the said test, all of them were panting and sore while I was perfectly fine). So what's really happening? Is my BFP really that bad, despite exercising regularly? Does my heart rate have anything to do with my BFP results? And what's with the low heart rate anyway? Thanks!
