There are few things in life more frustrating than waiting for the visual results of exercise to appear. Whether we verbalize it or not, we have all thought it before: “I know exercise works, but how much longer do I have to do this before I SEE it work?” However – as is the case with so much else in life – the lifestyle of exercise must create change on the inside before any kind of change on the outside can appear. That’s where understanding a little bit about what goes on in your body when you embark on a workout program becomes helpful: namely, these adaptations effect the body at the neurological, muscular, endocrine, and anthropomorphic levels.

The first change that occurs is at the neurological level. The body’s ability to lift heavier loads with training is due to “increased motor unit recruitment,” which occurs when the amount of muscle fibers that a given neuron innervates is increased-the more muscle fibers that fire at one time, the more weight you can lift!

The next adaptation the body goes through occurs within the muscle belly itself. Within each muscle group in our body, we have two basic types of fibers that are responsible for completing different activities. Specifically in regards to the type II fibers, chronic and progressive resistance training causes these fibers to grow in size, known as “hypertrophy,” which allows the body to lift heavier weight.

Third, the endocrine, or hormonal, system must undergo some changes. After each workout that you complete, testosterone and growth hormone are released in order to take protein and repair the muscle fibers that were damaged from the weight that you lifted. As a result, over time and repetitive bouts of resistance exercise, these hormones build your muscles stronger, leaner, and denser so that they can withstand more and more weight as you go through each workout of your program.

Lastly, the anthropomorphic, or body-shape, changes occur. As a result of all the internal changes that occur over months of regular resistance exercise, the body finally starts to take the desirable shape and appearance that you want. Your muscles literally turn your body into a fat-burning machine! Furthermore, since you have less fat underneath your skin, your muscle definition begins to appear more prominent, giving you an overall tighter, firmer, and slimmer figure. FINALLY!!
