There has long been debate over the argument “lighter=faster”. It’s a tough topic, too, as it can be sensitive and even insensitive.
Lighter=faster may have some truth, in the onset. Over time, however, this couldn’t be more false.
The fact is that while when we weigh less we have less body to propel forward–the concept of lighter=faster–the less we focus on weighing, the less muscle we have and thus the less resilience we have. Over time, as we lose muscle, our body composition will begin to change. Not only that, we rely on muscle for a healthy and vibrant metabolism, strong and durable bones and joints, regular hormones, powerful cognitive function, a functioning heart, energy and vitality and so much more. As we wear ourselves down, we find ourselves suffering, especially in the long term.
It’s one thing to focus solely on the present: weighing less may temporarily make you faster. We see this often with young adults (especially youth) who first start running and are quick. As they get older and their bodies change, there seems to be a shift in speed. But, this isn’t because they gained weight–it’s because they need to shift their training and focus on performance with the body they now have. And that’s where things get lost in translation.
If we try to stay light as we age, weighing your lowest will eventually just make you slower…not only in running, but in every facet of life. We NEED muscle and some fat to be healthy. Furthermore, without a healthy balance of muscle and fat, we can even lose our reproductive capability. The truth is: you can still perform optimally as you age without focusing on being your smallest because not only does being strong positively impact your chances of running in the future (and running fast in the future, at that) it can even help you run faster NOW. Muscle is the powerhouse of your body. It allows you to forcefully push off the ground, prevents injury (which sidelines you entirely), strengthens your bones and joints, improves your energy for workouts and exertion, improves your stamina, improves your endurance, heightens your athleticism, makes you more agile, prepares you for any and everything that comes your way on your run.
If the goal is to run long into life, we need to focus on sustainability and building a body that can thrive outside of running. Running fast in the short term due to being light will come with the detriment of sacrificing your health down the road. You’ll no longer be running. In order to run fast in the future, you need to build a base that can carry you through that period.
It isn’t about being light. It’s about being strong: a force of nature. You can use muscle and strength to your advantage and become the best runner you have ever been, in a way that allows you to run long term. Just ask me for more information! I’m happy to help.
