Why exhaustion doesn’t translate into weight loss

pexels-photo-703009.jpegHave you asked yourself why you’re exhausted after a workout but there is no visible result in the end? If you have at least some experience with heavy workouts you must have fallen into that trap.

In this blog post I will try to present all the information in easy to grasp examples, without going into to the usual fitness terminology.

In the previous post about the calorie balance we mentioned the overall activity of a single day. I will now present the activities from the same day as an example. They were – a full body workout, predominantly with my own weight, tennis, and a bike ride to the tennis courts and back. The important thing I want to emphasize here is that sometimes the activities, which we don’t feel as tiring are actually burning way more energy than workouts, which leave us exhausted. In addition, the latter type of exercise is often making us prone to overcompensate with food afterwards. We’ve exhausted all our willpower during the workout and we feel entitled to a big meal and a few treats after that.

So, here are the activities I practiced in that specific day. Plus, a detailed breakdown of calorie consumption and heart rate during my tennis practice.

The first thing to notice is that my leisurely bike ride burned almost twice as much as my HIIT at home, for the same time period. That surprised me years ago when I first noticed it.

The second point of interest is that, even though I don’t feel tired while playing tennis, which I can do for at least a couple of hours, without stopping, my heart rate tells a different story. It is almost constantly in the cardio zone and I am burning through those calories as in no other activity. At least not one, which I can sustain for so long with so little exertion.


After all, that’s the key – how long can you keep doing whatever you’re doing? It’s all in the math – what comes in and how much of it you burn.

So, take it easy, workout a little bit, get that muscle tone up, go have a walk with friends, ride a bike, live a life. Don’t run yourself down, just to have a “healthy” snack after that, which is twice the calories you burned in the first place.


P.S. That post took me awhile, because I want to break all the essential info in bite-sized chunks, which don’t go into too much detail, but are in the same time as objective and scientifically backed as possible.

Let me know if that suits you!
