Ive been in the Fitness Industry for the last 10 years,and have completed my Btech Degree in Sport and Exercise Tech.
The only advise i can give you is that every Joe soap out there has his own idea's of what works, be it info he got from a friend or info that he googled, the same thing doesnt aways work for everyone. In your case, you dont wanna do Triathlon's, and win the comrade's, you just wanna loose a few pounds, so go out get that bike, dont worry about your "correct heart rate" just go out and have a ride, whatever you do, you will still see results....because you have a sedentary lifestyle, and diet......most important of them all! what what you eat, you dont have to weigh your food, just be senceable, you know whats healthy and whats not.
But most of all, be consistant....just my 2c worth.
