This was week two of the Reconnect and Restore program where Michael Finnegan presented
on the female nervous system and its unique differences from male physiology. Michael, a
strength coach with 26 years of experience, explained that women are not small men and have
distinct neurological and hormonal variables that require different approaches to training and
recovery.
Female Nervous System Program
Spencer welcomed participants to the program and introduced Michael Finnegan as the
presenter for the session focused on the female nervous system. Michael emphasized that
women are not small men and highlighted the unique differences in how the female body
operates, including faster recovery from exercise and greater reliance on the parasympathetic
branch of the nervous system. However, he pointed out that the nervous system works with the
endocrine system of hormone and that there is continuous neurological feedback happening
between the two systems. He explained the role of hormones like adrenaline, noradrenaline,
and dopamine in the sympathetic and parasympathetic nervous systems and discussed how
these differences impact performance and recovery.
Nervous System and Hormonal Balance
Michael explained the differences between the sympathetic and parasympathetic branches of
the nervous system, highlighting how they work together as a continuum to regulate energy and
relaxation. The sympathetic system is the activated branch, and the parasympathetic is the
recovery branch. He discussed how hormones like estrogen and progesterone influence these
systems, particularly affecting women’s physiological and performance cycles. Michael
emphasized that training intensity and adaptation are limited by an individual’s recovery
capacity, stress levels, and hormonal balance, and he stressed the importance of understanding
these factors for effective coaching and performance.
Nervous System Balance and Performance
Michael discussed the importance of understanding the balance between sympathetic and
parasympathetic nervous system states, particularly in relation to physical activity and recovery.
He explained how hormonal changes affect performance in women, recommending monitoring
progress month over month rather than week to week. Michael also described the “wired and
tired” condition, highlighting how it manifests differently in men and women, with women more
likely to experience jaw tension, grinding, bloating, and racing thoughts, while men may show
anger and mood swings along with increased injury risk during warm-ups rather than main lifts.
Parasympathetic Balance for Women’s Health
Michael discussed the importance of balancing the sympathetic and parasympathetic nervous
systems, explaining how women typically struggle more with entering the parasympathetic state
which impacts areas like body composition, digestion, and libido. He emphasized that recovery
and relaxation are crucial for adaptation and success, particularly for women, and outlined eight
pillars of parasympathetic function including heart rate slowing, improved digestion, and better
heart rate variability. Michael noted that many women’s health issues, including menstrual cycle
dysfunction and decreased libido, can be addressed by achieving a more parasympathetic
state.
Nervous System and Hormonal Health
Michael discussed the impact of inflammation and hormonal changes on the nervous system,
particularly how women’s hormonal profiles fluctuate across different life stages including
menstrual cycles, pregnancy, postpartum, perimenopause, and menopause. He emphasized
that managing the nervous system from sympathetic to parasympathetic state is crucial for
health, noting that screen time and constant notifications can stimulate the nervous system and
interfere with recovery. Michael explained that creating boundaries around activities and sleep is
more effective than biohacks for improving parasympathetic function and answered a question
about workout recovery by describing signs of proper nervous system recovery including being
able to focus without being wired and avoiding post-workout cramping or neck tension.
Women’s Hormonal System Overview
Michael explained the hormonal system in women, covering key hormones including estrogen,
progesterone, testosterone, cortisol, adrenaline, insulin, thyroid hormones, melatonin, and
growth hormone. He discussed how estrogen and progesterone regulate the menstrual cycle,
while cortisol acts as an energy controller and is demand-based. Michael emphasized the
importance of proper sleep, particularly avoiding late-night screens which can kill melatonin
production and impact hormone balance. He concluded by explaining how negative factors like
poor sleep, chronic stress, and restrictive dieting can negatively impact hormones, emphasizing
the need to consider the entire picture including nervous system and exercise when evaluating
health.
Women’s Hormonal Profiles and Exercise
Michael presented different hormonal profiles in women, including the high-responsibility
workaholic, chronically dieting individual, and caregiving mothers, all of which lead to similar
nervous system issues despite showing different symptoms. He explained how hormonal
changes throughout a woman’s life affect these profiles and emphasized the importance of
proper sleep and recovery for optimal hormone response. Michael outlined a framework for
exercise programming that considers environmental factors, energy levels, nutrition, and stress
before choosing appropriate exercise tools and ensuring adequate recovery time.
Neurological Demand in Exercise Protocols
Michael discussed the hierarchy of neurological demand in exercises, explaining that low
systemic demand exercises are best for recovery, moderate demand exercises are suitable for
normal conditions, and high neurological demand exercises like barbell work are appropriate
when feeling good. He outlined two training protocols based on nervous system health, with
Protocol 1 allowing four weight sessions and two cardio sessions per week for healthy nervous
systems, and Protocol 2 limiting exercise to three days per week with lower intensity for
stressed or recovering clients. The discussion included questions about e-readers and sleep
with Michael clarifying that e-readers don’t have the same neurological impact as phones or TVs
due to their dull white light, and he provided guidance on estrogen detox and supplement
recommendations like magnesium and inositol for recovery.
