There is a lot of debate whether or not walking is as beneficial as jogging. I personally think one should try to get their heart rate much higher than what walking alone will do, and that is probably where you’re going to get your most dramatic results.
Walking is okay, and although more tiring walking in sand, it should be a better work out, and possibly easier on your knees and joints than concrete or asphalt. Heavier people might also have too much strain on their knees and might consider a recumbent bike to get their hear rate up until some of the weight comes off.
About six months ago, my brother noticed his heart racing a bit at times. He had some blood and heart tests done, which I think included a MRI. The doctor told him there was nothing wrong with his heart, but he needing to start jogging. Here’s how I remember everything.
He’s 48, and was 230 lbs. He’s lost 60 lbs in about six months, and has kept his weight at 170 for the last three months or so. He’s had his blood checked regularly since it is free when he donates, and after his running, he’s bad cholesterol has dropped significantly, well over 30 points in just two months, not sure how much more since then. I could be mistaken, but I think he’s lost over 50 points off of his bad cholesterol now. His good cholesterol has also went up, but can’t remember those numbers. The blood clinic he goes to checks for about a dozen different things, and just about everything is in the normal range for him now. How much his good and bad cholesterol were related to his weight loss, I don’t know. He jogs about 4 to 5 times a week, about an hour on each jog. It’s help his mood tremendously too. He gets that afterglow effect.
I have taken to jogging myself here lately, and don’t need to lose any weight, so will maintain my present weight. I had my blood work done before jogging, and will test my blood again soon, to see what kind of results I get from the jogging. I’m anxious to see if the numbers are as dramatic for me as they were for my brother without any weight loss.
I’ve been enjoying my jogs much more since the purchase of the Garmin Forerunner 305. You might consider getting something like this as well. It has the gps feature which accurately tells you how fast you’re going, your distance, and a great deal many other things along with a super accurate heart monitor. Right now, I’m alternating between jogging and walking until I can get my stamina more built up.
