Exercise Physiology Masterclass: Beginner to Advanced

Explore adenosine triphosphate, an organic compound that serves as the body's energy source for metabolic and biochemical processes, respiration, digestion, brain function, and physical activity.

Identify the types of energy systems, including the fourth creating system (EPCM), glycolysis, and the Arabic system.

Explains the ATP-CP (ABCP) energy system, where creatine phosphate rephosphorylates ADP to ATP in 0–30 seconds, powering sprinting and Olympic lifts, with creatinine as a waste product.

Explore glycolysis, the energy system powering eight to twelve rep sets lasting 30 to 75 seconds, as muscle glycogen converts to ATP and lactate fuels working and non-working muscles.

Activate the aerobic system for longer, low-intensity activity, where substrates such as free fatty acids and amino acids enter the Krebs cycle to produce ATP, with CO2 exhaled.

Explore fitness as the quality or state of being fit, the condition of being physically strong and healthy, and the ability to fulfill a task efficiently without too much exertion.

Explore the components of fitness, including strength, cardiovascular endurance, muscular endurance, velocity, speed, power, agility, reaction time, coordination, balance, accuracy, acceleration, body composition, flexibility, mobility, and stability.

Strength describes the amount of force a muscle or group can exert against any load, including body weight or equipment, using multiple muscle groups.

Power is the ability to generate force as fast as possible, emphasizing the speed at which you move body weight or any load, as in sprinting and fast lifts.

The lecture contrasts strength and power using pushups, showing a body-weight pushup versus an explosive pushup performed with greater speed.

Explore cardio as any physical exercise that raises heart rate, a cardiovascular movement aimed at increasing the heart’s capacity.

Explore different cardio types, including high intensity interval training, moderate intensity steady state, and low intensity steady state cardio, and learn how to adjust intensity within the same exercise.

Explore cardiovascular endurance by examining how efficiently the heart and lungs support exercise, and compare fatigue rates between runners with identical distance and intensity.

Explore body composition by comparing lean muscle mass to fat mass, showing how two people with identical weight can have different body compositions.

Differentiate fast twitch fibers and slow twitch fibers, and explain how fast fibers power strength and explosive movements with limited blood supply, while slow fibers support endurance with more oxygen.

Define what a joint is and explain how articulation connects two or more skeleton structures in the human or animal body.

Learn the difference between ligaments and tendons. Ligaments are connective tissue that connect bone to bone, while tendons connect muscle to bone.

Explore flexion and extension as the main joint movements, where flexion decreases the angle between body parts and extension increases it, demonstrated at joints like the elbow.

Identify hyperextension as excessive joint movement where a joint angle opens beyond 180 degrees. Recognize that some individuals are genetically hyper flexible with joints that extend past the straight line.

Explore abduction and adduction by defining movement away from and toward the body's midline, with raising the arms to the side as abduction and bringing them down as adduction.

Explore protraction and retraction by learning how the scapula, or shoulder blade, moves forward and backward along the shoulder girdle.

Explore elevation and depression as movements toward the upward and downward directions. Learn how elevating and depressing the scapula—shoulder blades—defines these terms in shoulder movement.

Explore supination and pronation, the forearm rotations that orient the palm forward or upward and backwards or downwards.

Explore inversion and eversion of the foot, defining inversion as turning the bottom of the foot toward the midline and eversion as turning it away from the midline.

Explore how rotation twists joints, focusing on hip and shoulder outward (lateral/external) and inward (medial/internal) rotations.

Master each exercise by understanding the target muscles and the client's objective and what they want to achieve.

Provide visual, auditory, and kinesthetic cues to help clients perform exercises consistently, using demonstrations, verbal guidance, and hands-on positioning.

Identify that optimal exercise depends on context and objective, not universal right or wrong forms, as demonstrations show neutral and rounded back deadlifts.

Movement encompasses any physical activity, voluntary or involuntary, planned or unplanned, which may or may not improve fitness. Exercise is a voluntary, repeated movement aimed at increasing fitness.

Understand concentric (positive) and eccentric (negative) phases by how the load moves: upward for concentric actions and downward for eccentric, with examples from barbells, cables, and bodyweight squats.

Learn how to load an exercise by adding external resistance beyond body weight. Explore equipment options such as barbells, dumbbells, cables, resistance bands, kettlebells, and sandbags.

Increase the load to lift more weight and get stronger, and to break plateaus when muscle growth slows, raise tension in the local muscle group to promote hypertrophy.

Explore progressive overload through increasing load, reps, volume, frequency, and density, plus tempo, stance changes, and advanced methods like eccentric overload and drop sets.

Explore voluntary muscle contraction as the deliberate, conscious activation of muscles to produce movement, including static and dynamic contractions.

Explore the differences between active and passive range of motion by comparing assisted and unaided hip movements to highlight voluntary muscle contraction and joint deflection.

Define the difference between mobility and flexibility. Illustrate that flexibility is a passive range of motion, while mobility is an active range of motion.

Explore the range of motion for a joint, illustrating how the elbow flexes from 0 to about 140 degrees and defines a joint's full movement potential.

Explore why range of motion varies across joints due to nervous system control and protective mechanisms, and how bone size and shape differences influence movement.

Case study examines a general population client seeking weight loss, prioritizing weight loss after fitness assessment and treating range of motion as a secondary focus.

We assess a wicketkeeper athlete from the women's cricket team and tailor a plan to improve hip and knee flexion for deep squats, while maintaining weight with a nutrition plan.

Explore how injury risk is predicted by multiple factors, illustrated by helmeted versus non-helmeted riders and a well-rested player, where any missing factor can raise risk.

Identify range of motion limits across joints with movement assessment; save time, but cannot always pinpoint whether the ankle, hip, or knee causes the issue.

Explore passive and active joint assessment: passive tests use external force to gauge range of motion with no muscle contraction; active tests rely on the client's movement with no force.

Explore static stretching and PNF stretching to improve range of motion, using holds and isometric contractions to gain 10–20 degrees, while recognizing no assessment protocol across athletic and senior populations.

Tailor assessment tools to each client—general, athletic, or senior—based on objectives and starting point, then adjust as they progress.

Nutrition drives muscle building and fat loss by balancing calories in and out and prioritizing protein intake of 1.5–2 g/kg, distributed across 4–6 meals.

Explain that nutrition comes from all foods and that junk food alone does not determine health. Emphasize long-term dietary patterns, caloric density, and overconsumption leading to overweight.

Develop confidence as a future personal trainer by debunking intimidation, valuing education and clear communication, and upholding ethical, evidence-based practice and responsible social media presence.

Stay skeptical and fact-check information about exercise physiology, review energy fundamentals and training myths, and commit to ongoing learning by following the latest scientific literature.

Kids can lift weights; weight training during growth can positively affect development as tissues adapt. It also improves stability, balance, and reaction time, and supports athletic performance.

Explore why sweating does not equal fat loss; true fat loss occurs on a prolonged calorie deficit, with fat excreted mainly as CO2 and bodily fluids.

Women can lift weights without becoming bulky; lower testosterone slows muscle growth, while weightlifting improves bone mass, daily movement, and can be paired with cardio for balanced fitness.

Compare the pros and cons of machines versus free weights for weight training, from beginner stability and control on machines to stabilizer activation and movement familiarity with free weights.

Explore multi-joint versus single-joint movements for hypertrophy, and learn to combine both in a program to engage smaller muscles often missed by one type.

Challenge the no pain, no gain mindset by showing that stopping before failure still promotes muscle hypertrophy in resistance training. Recognize that soreness is not a reliable progress indicator.

Rest days depend on the training program, intensity, and weekly recovery. If clients feel chronic soreness, poor sleep, or mood swings, reduce or skip workouts to aid CNS recovery.

Evaluate whether you can split workouts into two daily sessions; outcomes depend on nutrition and recovery, while general clients may succeed with one session unless recovery is solid.

Counter the idea that exercise justifies a bad diet; exercise burns about three to 400 calories per hour, far less than a slice of pizza, so diet matters.

Define tone as the appearance of muscle and fat, and show how muscle hypertrophy increases size while fat decreases under a calorie deficit, shaping a firmer look.

Explores whether you can be overweight and fit by discussing fitness components and body composition, comparing 100-meter sprinter and sumo wrestler, and noting risks of excess and visceral fat.

Explore whether training can alter muscle belly insertions, explain genetic limits, and show how hypertrophy and fat loss reveal defined chest, biceps, and abdominal muscles.

Explore how volume, frequency, intensity, and effort drive muscle hypertrophy with guidance on sets (15–20) and training twice weekly, rest intervals 60 seconds to 3 minutes, and stopping before failure.

Do not shock your muscles; they don't have a brain, so progressive overload over time drives hypertrophy by varying range of motion, grip, angles, or increasing load and reps.

Women and men do not need different exercise protocols; women can lift weights without becoming bulky, and cardio serves the heart and endurance regardless of gender.

Explain that there is no fat-burning zone; fat use occurs during longer activity, but heart rate alone does not determine fat loss. For most clients, blend cardio with resistance training.

Explore how fixed good or bad posture is questioned, define bad posture as a rounded upper back, and highlight that movement, not posture type, supports spine and joint health.

Compare running mechanics on ground and treadmill: ground runners lean forward with propulsion, while treadmill runners stay more upright with a gliding stride, and knee safety depends on joint capacity.

Explore optimum repetition range and debunk myths about light versus heavy loads; when volume is matched, high-rep and low-rep training yield similar muscle mass gains, while heavy weights boost strength.

Identify why certain gym exercises are contraindicated and can increase injury risk, such as behind-the-neck movements. Assess each client's range of motion, limitations, and strengths to personalize safe exercise prescriptions.

Explore safe exercise guidelines during pregnancy, covering nutrition, activity levels, trimester-specific safety, and examples like bodyweight moves and lightweight goblet squats.

Explore whether to keep a neutral spine while lifting weights, understanding neutral as a zone rather than a fixed position. Train with neutral, extended, or flexed spines to build resilience.

Train on an empty stomach if you feel comfortable, but for athletic goals eat carbohydrates before workouts to boost performance; for general clients, either approach may work.

Explain why spot reduction does not occur by showing that fat mobilization varies with alpha and beta receptors, with stubborn areas containing more alpha receptors leading to slower fat loss.

There is no exercise that targets belly fat; spot reduction does not exist. Crunches burn calories and help with fat loss when paired with a caloric deficit and healthy nutrition.

Explore warm up basics, including treadmill jog, static or dynamic stretching, and light-load rehearsal of the upcoming lift, and see how it raises temperature, heart rate, focus, and muscle recruitment.
