New to Insanity- Polar 4t hrm "In zone"
Hi Started Insanity training about 2 weeks ago. I bought a Beurer hrm and tried it for one day. Didnt like it at all. Too complicated to set up, but what i got from it was that my upper heart rate should be 187bpm. i am 42 and weigh 187lbs, 5ft 10. I took it back and got a Polar 4T which i love because its simple to set up…
