VITAMINS & MINERALS
WHAT:
Trillions of microorganisms (mostly bacteria) living in your gut
• ~30–100 trillion microbes
• Hundreds of different species
• Primarily located in the large intestine
* You are essentially a human microbial ecosystem
⚙️ WHAT THE MICROBIOME ACTUALLY DOES
1. Helps Digest Food
Especially:
• Fiber (which you can’t digest alone)
• Certain carbs (prebiotics)
* Produces short-chain fatty acids (SCFAs):
• Butyrate
• Acetate
• Propionate
These:
• Feed gut cells
• Reduce inflammation
• Support metabolism
2. Controls Immune System
• ~70%ish of your immune system is in your gut
• Microbiome “trains” immune responses
3. Gut-Brain Axis
Your gut communicates directly with your brain.
• Vagus nerve
• Neurotransmitters
* Gut produces:
• ~90%ish of serotonin
• Other mood-related chemicals
4. Impacts Energy & Metabolism
• Influences how you extract calories from food
• Affects insulin sensitivity
• Plays a role in fat storage
5. Affects Performance & Recovery
• Nutrient absorption
• Inflammation control
• Recovery speed
* Athletes with healthier microbiomes often:

* It’s not about eliminating bad bacteria, It’s about balance + diversity
🧱 GUT LINING
A thin barrier separating:
• Your gut contents
• Your bloodstream
“Leaky Gut” When damaged:
• Undigested particles enter bloodstream
• Triggers immune response
* Leads to:
• Inflammation
• Fatigue
• Digestive issues
🧠 MICROBIOME & INFLAMMATION
Chronic Inflammation Comes From:

• Stable energy
• Minimal bloating
• Strong immunity
Warning Signs
• Frequent bloating
• Irregular bowel movements
• Fatigue
• Food intolerances
MICROBIOME
💧 Hydration = Water + electrolytes in the right balance inside and outside your cells
Your body is 70%+ water, and that fluid is involved in:
• Blood flow
• Temperature control
• Nutrient transport
• Muscle contraction
• ATP production
* Even 1–2% dehydration can reduce performance noticeably
Cardiovascular Function
• Blood is mostly water
• Dehydration → thicker blood → harder to pump
Temperature Regulation
• Sweat cools the body
• Water loss = overheating risk
Muscle Function
• Electrolytes control contraction
*Imbalances cause:
• Cramping
• Weak contractions
• Poor coordination
Energy Production
• Cellular processes (ATP production) require fluid balance
* Dehydration = less efficient energy
🧂 ELECTROLYTES
*Water alone isn’t enough
Main Electrolytes:
Sodium
• Controls fluid balance
• Helps retain water
• Critical for nerve signals
* Most important during sweating
Potassium
• Works with sodium
• Muscle contractions
• Prevents cramps
Magnesium
• Muscle relaxation
• Prevents tightness/cramps
Calcium
• Triggers muscle contraction
* Water follows sodium
• Drink too much plain water ~ can dilute sodium
• Result = poor hydration despite drinking
🔄 FLUID BALANCE
Your body manages two main compartments:
• Intracellular (inside cells)
• Extracellular (blood, fluid outside cells)
*Electrolytes control where water goes.
🧠 SIGNS OF DEHYDRATION
Early Signs
• Thirst
• Dry mouth
• Slight fatigue
Performance Signs

Add for Training
• +16–32 oz per hour of exercise
Adjust For:
• Heat
• Sweat rate
• Body size

⚠️ OVERHYDRATION
Yes, you can drink too much water.
Hyponatremia
• Too much water, not enough sodium
* Symptoms:
• Headache
• Nausea
• Confusion
HYDRATION
Digestion = Breaking food down - absorbing nutrients - delivering them to cells
3 main stages:
1. Mechanical breakdown (chewing)
2. Chemical breakdown (enzymes, acids)
3. Absorption (into bloodstream)
*If digestion is off, nothing else works optimally
🛣️ THE DIGESTIVE PROCESS
1. Mouth
• Chewing breaks food physically
• Saliva contains enzymes (amylase) - starts carb digestion
* Carbs are the only macro that begins digestion here
2. Stomach
• Hydrochloric acid (HCl) breaks down food
• Protein digestion begins (via pepsin)
• Food turns into chyme
• Kills bacteria
• Controls release into small intestine
* Protein digestion = heavily stomach-dependent
3. Small Intestine
This is where most digestion + absorption happens.
Enzymes + Organs Involved:
Pancreas
• Releases enzymes:
• Amylase - carbs
• Protease - protein
• Lipase - fats
Liver + Gallbladder
• Produce & release bile
• Break down fats into usable form
• Carbs - glucose
• Protein - amino acids
• Fats - fatty acids
Large Intestine
• Water absorption
• Electrolyte balance
• Gut bacteria fermentation
* Produces:
• Some vitamins (like K, certain B vitamins)
🧬 HOW EACH MACRONUTRIENT IS DIGESTED
Carbohydrates
• Mouth (amylase)
• Small intestine - fully broken into glucose
* Fastest to digest - quickest energy
Protein
• Stomach acid + enzymes begin breakdown
• Small intestine - amino acids absorbed
* Requires strong stomach acid
Fats
• Mostly digested in small intestine
• Requires bile (from liver/gallbladder)
* Slowest digestion - longest lasting energy
⚙️ ABSORPTION
*** You don’t “use” what you eat, You use what you absorb
Absorption Pathways:
• Carbs ~ bloodstream ~ liver ~ energy
• Protein ~ bloodstream ~ tissues (repair)
• Fats ~ lymphatic system ~ slower release
🦠 THE GUT MICROBIOME
***Trillions of bacteria in your gut
• Helps digest food
• Produces vitamins
• Supports immune system
• Affects mood (gut-brain axis)
* A healthy gut = better:
• Digestion
• Recovery
• Mental clarity
⚡ DIGESTION & PERFORMANCE
Energy

🧠 NERVOUS SYSTEM & DIGESTION
“Rest and Digest” (Parasympathetic)
• Optimal digestion state
“Fight or Flight” (Sympathetic)
• Digestion slows or stops
*Stress = worse digestion
DIGESTION

PROTEIN
The goal is ultimately to accumulate enough high-quality stimulus while staying recoverable
That means balancing:
• Volume (total work)
• Intensity (load)
• Frequency (how often)
• Effort (proximity to failure)
📊 Training Volume (MOST IMPORTANT DRIVER)
Definition: Total hard sets per muscle per week
Optimal Range:
• 10–20 sets per muscle / week
Breakdown:
• Beginners: 8–12
• Intermediate: 10–16
• Advanced: 12–20+
* More is NOT always better—recoverable volume wins
🏋️ Intensity (Load)
Ideal Range:
• 65–85% of 1RM
This typically falls into:
• 6–15 reps per set
* You can grow outside this range, but this is the most efficient zone
🔁 Reps in Reserve (RIR) / Effort
How close you train to failure matters more than reps alone.
Ideal:
• 0–3 RIR (near failure)
Practical:
• Compounds: 1–3 RIR
• Isolation: 0–2 RIR
* Training too far from failure = weak stimulus
* Training to failure every set = recovery issues
🔄 Training Frequency
Optimal:
• 2x per muscle per week
Why:
• MPS spikes last ~24–48 hrs
• More frequent stimulation = more growth cycles
⏱️ Rest Periods
Hypertrophy Sweet Spot:
• 1–3 minutes
• Short rest → more metabolic stress
• Longer rest → better performance on next set
* Slightly longer rest = better total volume output
🧬 Exercise Selection

BUILDING MUSCLE
Macros & pathways
🔹 Energy = ATP
Everything you do—lifting, running, even thinking—is powered by ATP (adenosine triphosphate), the body’s energy currency.
• ATP is constantly being used and regenerated
• The body uses macronutrients to rebuild ATP
• Three energy systems control how fast ATP is produced
🔹 Macronutrients
1. Carbohydrates
• Broken down into glucose
• Stored as glycogen (muscles & liver)
• Fastest and most efficient energy source
Best for:
• High intensity training
• Speed, power, HIIT
• ATP-PC (support role)
• Glycolytic system (primary)
• Oxidative system (secondary)
* Key idea: carbs = quick energy
2. Fats
• Broken into fatty acids
• Huge energy reserve in the body
• Low intensity
• Long duration activity
• Oxidative (aerobic) system only
* fats = slow, long-lasting energy
3. Protein
• Broken into amino acids
• Not ideal for energy (used mainly for repair)
Used when:
• Starvation
• Extremely long duration exercise
• Low carb availability
* protein = emergency fuel
🔹 The 3 Energy Systems
These systems work together, but one dominates depending on intensity + duration.

carb sourcing
🧨 Phase 1: Acute Stress Response (During + Immediately After Training)
What happens:
• Muscle fibers experience microtrauma
• Glycogen stores are depleted
• Nervous system fatigue accumulates
• Stress hormones spike (cortisol, adrenaline)
Key signals activated:
• Inflammation begins
• mTOR signaling starts
• Satellite cells are recruited
🔬 Phase 2: Inflammatory Response (0–24 Hours)
This is often misunderstood—inflammation is necessary.
What happens:
• Immune cells (macrophages, neutrophils) rush to damaged tissue
• Remove damaged proteins and cellular debris
• Release growth factors
Key molecules:
• Cytokines (IL-6, TNF-α)
• Reactive oxygen species (ROS)
Controlled inflammation = triggers repair
Excess inflammation = slows recovery
🧬 Phase 3: Repair & Regeneration (24–72 Hours)
• Satellite cells activate and fuse with muscle fibers
• New protein structures are built (MPS elevated)
• Collagen synthesis increases (connective tissue repair)
Energy demand is high / nutrition becomes critical
📈 Phase 4: Adaptation / Supercompensation (48–96+ Hours)
The body doesn’t just repair—it overcorrects.
Results:
• Muscle fibers become thicker
• Neural efficiency improves
• Energy systems become more robust
* This is the performance gain window

“How long can you sustain effort?”
What It Is
• Ability to perform repeated contractions over time
Primary Drivers
• Fatigue resistance
• Aerobic + anaerobic efficiency
Training Style
• Light–moderate loads
• High reps (15–30+)
• Short rest
Energy System
• Glycolytic + Oxidative
Adaptations
• Increased capillary density
• Improved metabolic efficiency
Examples
• High-rep circuits
• Bodyweight training
🧠 RELATIVE STRENGTH
“Strength relative to bodyweight composition ”
What It Is
• Strength ÷ body weight
Why It Matters
• Critical for athletic performance
Training Style
• Strength training + bodyweight control
Examples
• Pull-ups
• Gymnastics
• Combat sports
⚖️ ABSOLUTE STRENGTH
“Total force potential”
What It Is
• Maximum total force output
Examples
• Powerlifting totals
• Strongman events
🧩 FUNCTIONAL STRENGTH
“Strength that transfers to real world movement”
What It Is
• Strength applied across movement patterns
Focus
• Stability
• Coordination
• Multi-joint movement
Training Style
• Compound lifts
• Unilateral work
• Movement-based training
Examples
• Lunges
