Hi,
I recently moved from Polar watches to 735xt, and really like it so far:)
My question is, is there any way to "lock" the heart rate into a certain zone during an activity? I mean, I would like to do a heart-rate based training, like 10 min warm-up in Zone1, 20 min easy-jog in Zone2, 30 min aerobic-jog in Zone3, and set alerts based on HR in each period. I found the alert function in this watch, but couldn't figure out how to change the alert threshold during an activity.
