Lesson 2 • Health Screening and Baseline Assessment

Covers pre-exercise health screening tools and initial fitness testing protocols. Ensures safe program entry and establishes measurable starting points.

Lesson 3 • Understanding Physical Fitness Components

Defines the five health-related fitness components and their roles in overall wellness. Provides the conceptual framework used throughout the course.

Lesson 1 • Structuring a Cardio Program

Applies frequency, intensity, time, and type principles to build weekly cardio plans. Integrates warm-up and cool-down protocols for safety.

Lesson 2 • Cardiovascular System and Exercise

Explains how the heart, lungs, and blood vessels respond to aerobic exercise. Grounds cardio programming in physiological understanding.

Lesson 3 • Interval Training Methods

Introduces high-intensity interval training and steady-state contrasts. Students apply interval protocols to accelerate cardiovascular gains.

Lesson 4 • Heart Rate Zones and Intensity

Defines five heart rate training zones and their physiological targets. Students use zone-based intensity to guide cardio session design.

Lesson 1 • Resistance Training Equipment and Setup

Introduces free weights, machines, cables, and bodyweight tools. Teaches proper equipment selection and safe gym environment navigation.

Lesson 2 • Muscle Physiology and Strength Basics

Covers muscle fiber types, motor unit recruitment, and hypertrophy mechanisms. Provides the biological rationale for resistance training choices.

Lesson 3 • Designing a Resistance Training Program

Applies split routines, full-body formats, and periodization basics to program design. Students build a complete multi-week resistance plan.

Lesson 4 • Sets, Reps, and Load Selection

Explains rep ranges, set volumes, and load percentages for different training goals. Students match loading parameters to strength, hypertrophy, or endurance targets.

Lesson 1 • Recovery Strategies and Tools

Introduces foam rolling, massage, cold and heat therapy, and active recovery. Students build recovery protocols that reduce soreness and prevent overtraining.

Lesson 2 • Integrating Recovery into Training Plans

Schedules recovery days and modalities within weekly training cycles. Balances training stress and recovery to maximize long-term adaptation.

Lesson 3 • Stretching Techniques and Protocols

Covers static, dynamic, PNF, and ballistic stretching methods with timing guidelines. Students select appropriate techniques for warm-up and cool-down contexts.

Lesson 4 • Mobility Drills for Key Joints

Targets hip, thoracic spine, ankle, and shoulder mobility with specific drills. Directly addresses common mobility restrictions that limit exercise performance.

Lesson 1 • Pre- and Post-Workout Nutrition

Specifies nutrient timing strategies before and after training sessions. Optimizes performance output and recovery speed through strategic meal timing.

Lesson 2 • Hydration and Electrolyte Management

Covers daily hydration needs, sweat rate estimation, and electrolyte replacement. Prevents performance decline and health risks from dehydration.

Lesson 3 • Caloric Needs and Energy Balance

Calculates total daily energy expenditure and adjusts intake for goals. Students determine caloric targets for fat loss, maintenance, or muscle gain.

Lesson 4 • Supplements and Performance Aids

Evaluates evidence for common supplements including protein, creatine, and caffeine. Students distinguish effective aids from unsupported products.

Lesson 1 • Behavioral and Lifestyle Factors

Addresses sleep, stress, and habit formation as drivers of body composition outcomes. Integrates behavioral science into sustainable weight management.

Lesson 2 • Measuring and Interpreting Body Composition

Compares skinfold, bioelectrical impedance, DEXA, and circumference measurement methods. Students select appropriate tools and interpret results accurately.

Lesson 3 • Muscle Gain and Body Recomposition

Outlines conditions for simultaneous fat loss and muscle gain in specific populations. Guides programming for lean mass accumulation with minimal fat gain.

Lesson 1 • Designing Performance-Oriented Programs

Combines strength, power, SAQ, and endurance into periodized performance programs. Students build a complete athletic development training block.

Lesson 2 • Power and Explosive Training

Introduces plyometrics, Olympic lifting derivatives, and medicine ball work for power development. Builds rate of force development for athletic performance.

Lesson 3 • Functional Movement and Core Stability

Defines functional fitness and trains core stability as the foundation of movement quality. Connects core strength to injury prevention and athletic output.

Lesson 4 • Speed, Agility, and Quickness

Develops linear speed, change-of-direction ability, and reaction time through drills. Applies SAQ training to sport-specific and general fitness contexts.

Lesson 1 • Common Exercise-Related Injuries

Surveys overuse injuries, acute strains, sprains, and joint issues common in fitness training. Builds recognition skills for early intervention and referral.

Lesson 2 • Warm-Up and Cool-Down for Injury Prevention

Designs evidence-based warm-up and cool-down sequences that reduce injury risk. Connects tissue preparation and post-exercise recovery to long-term joint health.

Lesson 3 • Sustaining Fitness Across the Lifespan

Adapts training principles for aging, life transitions, and long-term adherence. Builds a mindset and strategy for lifelong physical activity engagement.

Lesson 4 • Training Load Management

Applies acute-to-chronic workload ratio concepts to prevent overuse injuries. Students monitor and adjust training loads to stay within safe progression zones.
