I think that it could be boiled down to three questions that I am currently trying to answer. And while I like both, doing both, seems senseless. I mean, what do I do, jog one and then day cycle the next?
It is a duplication of equipment that I would need for something that I could achieve with just one. And cycling is more of an upfront cost.
- Which one burns more fat in less time?
- This is the big one for me. I have less time, and that means it needs to count. The question is, while I can go further faster while biking, will it be less beneficial to me as a whole? I tend to think that it will be less beneficial.
- Which one is harder on my body
- In the past this has always been jogging, but, in recent years, whenever I get on a bike I end up with knee pain.
- How much distance and or time do I need to invest in a good workout?
- This really seems to be a question that nobody has an answer for. And honestly, it shouldn't be too hard to calculate.
- In the past I have lost more fat and weight tracking my calories than by actually working out.
I have often read that a "good workout" only depends on your fitness level and intensity.
I feel that with the goal of burning fat, either exercise will work, granted I approach it the right way. There is a target heart rate zone, that is to say, one that will burn more fat. Taking that as a starting value I think that it is safe to say that I could reach my target heart rate with either cardio exercise.
Since I have let myself get a little bit out of shape. And since jogging seems like it will rip hurt more than the other, for me a fat burning exercise, it would probably be easier to maintain that on a bike.
I know that it may seem silly, but the way that I see it is that if you're putting in the time and effort you may as well get every bit of benefit you can out of your exercise.
