When it comes to training, there's a certain point where your body will need some sort of change or variation from what you are currently doing. Why does this happen? Well, our bodies are very adaptable. This means that while something may seem difficult at first if you continue to do that same movement or training, your body will adjust, and it will become easier. This sounds great initially, although, as you have probably noticed, you reach plateaus in your training. Either you stop running that mile faster, or you can't lift that one more pound on the bar. So, what do we need to do to get the results we want? We have to slightly modify our training and add a new stimulus so our body can improve.
