I got this Polar FT4 heart rate monitor in July of 2012. Since then, I have used it off and on and I am really impressed with the quality. I did have to change the battery recently after not using it for a long time but that was easy to do.
Anyway, it keeps beeping today so I hope it is not messing up!
Time of day:20:24
In zone: 00:09:37 I thought I was in Zone more than that but I kept things slower today to be safe with my knee.
Average heart rate: 103
Maximum heart rate: 141
I walked on the treadmill for 25 minutes, rode the bike for a few minutes and did this Fitness Blender Upper Body Stretching Routine.
Morning work outs are working best for me. I get the exercising done before I can get side tracked!
