Unit Plan 7 (Grade 8 PE): Fitness Circuits & Training Intensity

Focus: Use fitness circuits (cardio, strength, core, agility) to sustain moderate-to-vigorous physical activity (MVPA), recognize training zones, and make proactive adjustments to workload using RPE/heart rate and basic fitness principles.

Grade Level: 8

Subject Area: Physical Education (Fitness Training • Health-Related Fitness • Self-Monitoring)

Total Unit Duration: 5 sessions (one week), 45–55 minutes per session

I. Introduction

Students move beyond just “getting tired” in workouts and begin training intelligently. Through structured fitness circuits, they practice sustaining MVPA, using rating of perceived exertion (RPE) and heart rate checks to understand whether they are in light, moderate, or vigorous zones. They learn key fitness principles like FITT (Frequency, Intensity, Time, Type), overload, and progression, and practice adjusting work/rest, pace, and exercise choices so circuits are challenging but safe. By the end of the unit, students see themselves as self-directed trainees who can read their own bodies and make smart training decisions.

Essential Questions

• What does it mean to be in moderate-to-vigorous physical activity (MVPA), and why does that matter for health and performance?
• How can I use tools like heart rate and RPE (how hard it feels) to monitor and adjust my workout intensity?
• How do FITT, overload, and progression help us design safe, effective workouts instead of random exercises?
• How can I adjust workload (speed, reps, rest, exercise choice) to match my own goals, strengths, and needs?

II. Objectives and Standards

Learning Objectives — Students will be able to:

1. Participate actively in fitness circuits and interval warm-ups, staying in MVPA for most of class with minimal standing around.
2. Use heart rate checks and an RPE scale to monitor intensity and recognize light, moderate, and vigorous effort in real time.
3. Adjust pace, reps, rest, and exercise options to keep training intensity in a desired zone, based on personal fitness level and goals.
4. Explain and apply key fitness concepts (components, FITT, overload, progression, specificity) when describing or modifying a workout.
5. Reflect on their own training data and experiences to identify strengths, challenges, and next steps for their personal fitness.

Standards Alignment — 8th Grade (SHAPE America-based custom)

• PE:S3.8a – Sustained Engagement in Moderate-to-Vigorous Activity Participate actively in moderate-to-vigorous physical activity for most of class time and demonstrate the ability to sustain effort across longer intervals or game play.
  • Example: During continuous small-sided games or fitness circuits, a student stays engaged, limits standing around, and completes all rounds with evident effort.
• PE:S3.8b – Self-Monitoring Activity Intensity & Adjusting Training Independently use tools such as heart rate, perceived exertion, or step counts to monitor activity intensity and adjust pace, duration, or workload to match specific fitness goals.
  • Example: A student uses an RPE scale to ensure that interval runs stay in a desired intensity zone and adjusts rest or speed accordingly.
• PE:S3.8c – Applying Fitness Components, Principles & Types of Training Explain and apply health-related fitness components and training principles (FITT, overload, specificity, progression) in designing or evaluating workouts.
  • Example: Students can explain why a mix of cardio, strength, and flexibility exercises is included in a weekly plan and how increasing sets or time creates progressive overload.

Success Criteria — Student Language

• I can stay moving and engaged in fitness circuits for most of class, with only short, purposeful rest.
• I can use an RPE scale and simple heart rate checks to tell whether I am in light, moderate, or vigorous intensity.
• I can adjust my workout (pace, reps, rest, or exercise choice) when I notice I’m working too easy or too hard.
• I can explain what FITT, overload, and progression mean and give an example from one of our circuits.
• I can describe at least one training zone and how it connects to my personal fitness goals.
