Ask yourself this: why wouldn't the human body be capable of the incredible feats that you are demanding of it? For millions of years, people evolved to survive and thrive in the cruel, unforgiving natural world. When there is pressure on you to push yourself, you better believe that you will push yourself – and it is only then that you will uncover your true potential. Read up sometime on the superhuman accomplishments of soldiers in battle down through the ages. The 2,000 years or so that make up our modern era haven't quite degraded our bodies beyond the point of this superhuman potential. It's just a matter of making the most of what you have!
Think about your grip. It should be strong, one of the most impressive parts of your body, just like it is for a baby. Squatting (even over extended periods – think hours) should also be possible for you, because that is the way our ancestors ate their meals and chatted with each other.
Long-distance runs and long-distance walks are should also seem normal to us, and when we want to sprint, we should be able to – just our ancestors had to, covering miles upon miles daily in search of food and bursting away from lions and elephants at any hint of danger. Your movement fluidity will come with training, and I can help you to rediscover it if you feel like you have lost it (or if you feel like you could be doing even more than you are doing already!).
Every single day, we ought to be using our bodies, turning it this way and twisting it that way, leaning over and squatting down, keeping our muscles active so that they don't even come close to stiffening to the point of pain. Fall down? Stand back up! This is all part of the learning process, and the right pain can mean that you are on track to true growth and progress in your fitness journey.
Your body is a magical thing, an incredibly adaptive tool capable of feats the likes of which you may never have considered possible. It all starts with your hands and your feet: tight, overbearing shoes often lead to damage in your foot, including arch collapse, and misuse or under-use lead to weak grips and poor neuro-connections.
Remember this: there is nothing that you can't re-learn. Your brain has simpyl gotten into the habit of laziness, picking up on the lessons that it doesn't have to do anything with regards to your neural pathways, putting your but to sleep, damaging your lower back. Our modern lifestyles may have damaged us, but they haven't broken us.
Don't lose hope.
No matter how old you are and no matter how you feel about your health, you can still adapt to a healthy, active lifesyle.
It starts with a single movement. From there, keep it going. Amp it up. Walk this way. Crawl over there. Squat. Jump!
Before you know it, you will be deadlifting heavier weights – and with greater ease. You will be pushing and pulling with your upper body, and you will be rotating your torso quickly and smoothly. You are going to look and feel your best in no time at all, and I am going to show you the way. This isn't just personal training; it's personal rediscovery.
