Heart rate training

Brown_Eyed_Beauty

I just got a heart rate and gps watch. I was wondering if anyone else has tried this type of working out?

I'm mainly walking and working up to jogging. I also plan to use it when I do videos and such to make sure I don't over do it. (I've hurt myself in the past)

So far I really like it. The watch is a polar PT60. Got it on clearance at best buy (yay). Any advice would be great because I'm still new with working out again in general.
Thanks bunches!
