This question seems even more relevant when, according to the running machine, I used up about 422kcal in my 50 minute run and this is about the same as I use on the cross trainer which leaves me feeling much less knackered. Is it possible that these calorie counts on the machines are hopelessly inaccurate?
Well of course they are. But according to the Men's Health magazine website, I'm burning more calories because I'm unfit than I would if I was fit. Which seems like a pretty good reason to not overdo the exercise and not get too fit. Kerching!
So, after 50 minutes running, the middle section of which was relatively fast, how did I feel?
1. I walked from the treadmill to the front desk of the gym area in ordeer to sign out. This walk involved quite a detour as my legs seemed intent on not keeping to the most direct route.
2. Walking down the stairs in the sports centre involved a certain amount of legs feeling like jelly, so I held onto the handrail. A bit.
3. Walking across the central concourse of the sports centre felt pretty good. It often does for some reason. I was feeling quite perky and bouncy. In some way the bottoms of my feet felt rounded and like they worked particularly well as feet.
4. I left the building and walked up a slight incline. My hips felt stiff and achy.
5. I walked along the street to our house. Feeling quite knackered now. Passed a blind lady using her stick to walk quite briskly along.
6. Feeling impressed by blind lady and wondered how it must feel to walk around with reduced vision. Had forgotten about my achiness.
7. Walked along the pavement for 30 paces, with my eyes closed, to see if I could walk in a straight line.
8. Opened my eyes. Luckily still on the pavement. Decided to stop being a weirdo. All feelings of achiness/ exercise euphoria completely vanished.
So I reckon the after-gym glow and wolg lasted about 5 minutes altogether. Hardly seems worth it.
