We often get caught up in the minutia of training. There are so many variables in training it is easy to lose sight of the big picture. But panning away from your training picture is very important. What you are doing today is a single brick in the (hopefully) great wall of your training. Training is a life-long endeavor. At least it started that way.
You needed at least a year to learn how to walk. It took you two years to climb a ladder. But you worked at it each and everyday. You slowly developed the ability to do these complex movements over time when your brain and the neurological control was most malleable. Your physical training as an adult is similar. We can't expect dramatic changes in a couple of weeks. Our bodies will gradually change, but it takes time.
One workout is not going to make you. It is simply another brick in the wall. The wall will take form and look like a wall only after you lay a series of foundational bricks. From here, more bricks can bring height to the wall, that is, your body will get closer to where you want it to be.
Here are a few things to ponder and to help keep a big picture perspective:
Your basic movement patterns are constantly changing- usually for the worst. Time should be invested regularly in maintaining or improving basic movement patterns.
Your are a complex biological organism. How you respond to stress differs from anyone else. I cannot predict what will happen with your training. That is why it is a process of: assess, train, reassess, train, reassess, train...etc.
Too much of a good thing is bad. Over training and repetitive stress can accumulate and be detrimental to your body. But, often a high volume of training and repetitive motions are used in training.
Sometime you need to take one step back to take two steps forward. This is easier to do when you plan on it. Even professional athletes take a break for weeks or months at a time.
One workout, in the big picture, won't make you (only one of thousands of bricks). But, it can break you (set you back). Have that mentality going forward.
Keep asking yourself "what is my weakest link" and regularly address it.
