This is a classic question I always get asked and one where people always get surprised when hearing my answer. Which is that for losing weight I put more emphasis on weight training.
Running is great and something I love to do but I do not run to lose weight. I run for other reasons, like to improve my cardiovascular condition, to disconnect and to prepare myself for future races. Because, like I have stated various times in my blog, the body is the best machine you will ever have. It is designed for efficiency, meaning that if you do the same thing over and over again, the process will become easier. So, this is good if your aim is to try to win a race but it is not good if your goal is to lose fat. For example, did you know marathon runners spend 30% less energy running a marathon than a normal person (1). Even do you are doing the same distance, the marathon runner is still burning or spending 30% less, how can this be? Well, it could be for various reasons like running technique and weight, but the most important one is that the metabolism has become more EFFICIENT. So if you run everyday for 40 minutes, your body is going to get more efficient and you are going to burn fewer calories. That is why I sometimes tell people who only run to lose fat that, instead of just slogging away to lose 300 calories, they can just eat 300 fewer calories per day and get the same result.
Weight training is different because, first, you are creating muscle. Muscle will elevate your metabolism, remember, most of the calories we burn throughout the day are not thanks to the sports we do but because of our metabolism. Also, every time we do weight training we create mini-micro tears that need to be repaired. This process requires energy, meaning we are burning calories. And let us not forget that strength training is considered anaerobic training because it is high in intensity. Exercises high in intensity have been shown to accelerate metabolism for up to 72 hours after the workout due to the effects of excess post exercise oxygen consumption (2).
In conclusion, running is a great activity and something that I usually recommend people to do and of course it can help in losing weight but, if you ask me, weight training is even better for this task.

Now with weight training
I will explain that later but first I want to explain some terms.
Aerobic – meaning your body gets its energy through the use of oxygen. When you are in aerobic the body´s prefer source of energy is ¨¨. Basically during the whole day we are in ¨aerobic¨, so we are burning fat the whole day. So, technically it is a myth when you hear people say ¨to burn fat you have to run more than 40 minutes¨, because you are burning fat throught out the day.
Anaerobic- without oxygen
