I am 38 year old male ,not active in sport , smoker , and occasionally drink few beers, but I am in need to improve my fitness and I went in gym and I started to use treadmill.My goal is to get 2 mile for 18:18. OK however i started to run and my time was over 20 minutes , but problem is I got heart rate during running around 192, as well as my heart rate stayed around 115 three hours later.I am little bit nervous about my goal because I have to get it( job req.).Please could you tell me is that slow recovery dangerous sign , or I am just not fit enough.One more think , might be important, mu heart rate in rest is mostly between 80-100. Thanks in advance for your time to give me an answer.
