Endurance and hard work are not things which come naturally to all of us. Indeed, there are many who, when faced with a particular task, will go at it with the zeal of someone who is possessed initially and will find themselves flagging very shortly afterwards. This makes every task a lot harder to complete, because they find they are in pain or their body won’t do what they want it to.
This is an issue of “core fitness”. Your body is built in a certain way, which requires it to place quite a bit of pressure on the muscles that are closer to the center. Try standing up for twelve hours. Nothing more than that, just standing up. Your legs will get tired, because they need to be active, but you will also notice that you get tired in other areas too.
This is because, no matter what you are doing – unless you are lying down and resting – you will be using your core muscles in order to make everything do what it needs to do. People with poor core strength will find everything much more difficult because they are unable to rely on the core muscles to do everything they have to do, and they will tire much more easily.
If you work on your abdominal muscles you will find that things get easier. You will be able to do even the most basic task better, for longer and at a more intense level the better your core strength gets – and as a result, you will feel a lot fresher and accumulate fewer twinges and muscle pulls
