Every car has a maintenance schedule. Every 8000km, I have to perform the recommended maintenance, whether it be something as simple as changing the oil and filter, or a little more in-depth, like inspecting the exhaust and suspension system.
If I don’t perform the maintenance when it’s scheduled and keep putting it off, then trouble will be coming my way. If I don’t replace the oil for 50,000km, my engine might seize and I’ll be shit of out luck – and money.
Your body is a machine, and it needs some basic maintenance on a regular basis as well.
Daily maintenance includes – properly warming up, stretching, lacrosse ball work, foam rolling, staying hydrated, eating well, sleeping well, etc.
Annual maintenance includes – body composition tests, blood work (to check progress), etc.
I would much rather spend the extra time and money keeping my body tuned up, than waiting for an injury to happen. If I keep putting off the maintenance, it will end up costing me twice as much anyway.
