2. FITNESS LIFE
• When the quarantine started ... I really felt locked up, bored, out of focus or out of fuel.
But I found something that filled me with energy and that became a habit, exercising
at home, but before starting I began to inform myself with the fitness life coaches, they
all repeated this word a thousand times, MOTIVATION.
• And I feel what they refer to, I generate a discipline in me, I feel more energetic, I want
more and more, I like how my body feels.

3. REWARD
Our attention span can detect possible rewards
(in this case feeling stronger or healthier). How
do we do to stay focused, when there are various
stimuli such as (stress, cell phone, food, among
others)? Motivation comes into play.

5. DOPAMINE
Which is unpredictable for learning,
attention and memory.
During this process, the neurotransmitter
Dopamine is generated. As we saw in the
course, this is important to maintain a
sustained focus of attention for a time, to fix
learning and knowledge in long-term
memory.
Motivation "motive for action" is reflected at
the cerebral level, by the ascending reticular
system (sraa), it travels its way in the
dopaminergic pathways that begin in the
ventral area and amygdal system, where it is
evaluated by the forces called pleasure - pain,
but in this case we are going to talk about
pleasure, since the exercise in this case is a
source of it, my tonsillar system interprets it as
a possible reward. Here the information is
directed, nucleus accumbens (main
dopamine-releasing nucleus).

6. What it does is create that expectation
that something important is going to
happen or of wanting to get a reward.
It produces other neurotransmitters
that further fuel this sensation.
Reaches the frontal lobes, where it is
interpreted, as fuel, to maintain
sustained tension and will make us
feel the sensation of effort.
Finally, when we achieve this reward
(to achieve an objective: to feel
stronger). A pleasant sensation of
relaxation produced by another
neurotransmitter Serotonin is
obtained. Finally said process is
completed.
