An important distinction to make before we can begin a conversation about strength and power is that of training versus working out.
Training is the implementation of a plan, or a specific strategy to achieve your goal. It is regimented, structured, and consistent in it’s methods and tools.
Training effectiveness is determined by numerical progress and can be measured by physical adaptations that include weight, body fat percentage, 1 repetition maximums, maximum repetition testing, timed trials of various sorts. Training is typically performance based and tested and retested.
Training strength in fitness is how long-term progress is made.
For most people, working out is regarded as any time you do something active with the intention of getting closer to achieving your goal, whatever that may be. While this may have an air of truth about it, it doesn’t tell the whole story.
In reality, working out is any series of compiled activities that generates a feeling of fatigue, exhaustion, sweatiness, and sometimes soreness.
Working out is effective for challenging yourself aerobically/metabolically and can be helpful in increasing your work capacity, endurance, and your daily energy expenditure (burns extra calories), but not necessarily your long-term results at it takes nothing but that day into account.
This is effective in the short-term, day-to-day, but not effective for the long-term.
