Just like many medial drugs, the effect of training is dose dependent. You need to at least meet minimum thresholds of dosage to expect to realistically see results from the training. Frequent, regularly recurring doses are necessary to expect to see the results that you want. Regardless of whether you’re training for fitness, speed, strength or weight loss, your training is never done. It is a continual process that is just as much about the process as the destination. Just like taking a medication, the training has to become a regular part of your life, a habit, if you are realistically expecting to see long term sustainable results. If training stops, detraining can occur very quickly and you may lose what you have gained.
