As a noun 'objective' means 'a thing aimed at or sought; a goal'. When it comes to our commitment to physical improvement we most likely have a goal, something we are aiming for or something that we seek. For some it might be a specific task or performance, for others it might be body composition or rehabilitation from an injury. It makes sense then that our training should be objective based.
This means it should be steering us towards the outcome we are hoping for. Our training should be leading us down the path to this objective and we should be able to see the how's and why's of what we are doing as they relate to it. If what we are doing isn't based on our objective, the reason we are doing it in the first place, then why are we even doing it? Training for trainings sake will be short lived, unfulfilling and ultimately a bit tedious. Achieving our objectives and recognising the outcomes of our hard work will keep us motivated, on point and focused.
Whatever it is you seek from your training, programming or coach it should be what influences what you do the most. Will the thing you are doing, being asked to do, get you to where you want to be. Setting these objectives might be easy for some and more challenging for others. A lot of people we train have a performance marker in mind: a sporting event or season, a test or a particularly life event. Others have a more long term objective: body composition or weight loss, maintenance of ability or rehabilitation from an injury.
Each given objective will have unique elements required for its success but also some cross over elements with other outcomes. Someone looking to pass military selection and someone looking to compete in CrossFit style events will both need to squat. The movement pattern will be the same. The loading, object and rep scheme would all be different because a different outcome is required.
Even more specifically someone looking to hit a personal best on their 10k would train different to someone preparing for a marathon and someone looking to compete in the 400m. Although a shared modality of running the energy systems, physical requirements and preparation needed are all very different.
Identifying what it is you want from training and setting a timeline, creating a plan and actioning it is the key to success with improving your physical capabilities. Don't fall down the hole of just training for the hell of it.
