I've used my Trex-3 over the last year and lost 70lb while going from 33% body fat down to 12%. I just picked up Garmin vivo 6 and this was my 1st workout with it. 1hr on stair master at speed 12-15 like normal. I have my user profile the same on garmin connect & the Zepp app for amazfit. 31m, 5'6, 142lb. Have it set for left arm and both on securely without too much pressure to cause red lines. Do I just need to wait about a week to start trusting results for it to calibrate to me specifically maybe?
