Circuit, Weight and Plyometric Training

This lesson covers three training methods required by the AQA GCSE PE specification (3.1.3): circuit training, weight training, and plyometric training. For each method, you need to know the definition, how to set it up, the advantages and disadvantages, and who would benefit most from using it.

Circuit Training

Definition

Circuit training involves performing a series of exercises (stations) in order, with each station targeting a different muscle group or component of fitness. The performer moves from one station to the next with minimal rest between stations, typically completing the full circuit 2–3 times.

How to Set Up a Circuit

1. Select 6–12 stations (exercises), ensuring they target different muscle groups or fitness components.
2. Arrange the stations so that consecutive exercises do not work the same muscle group — this allows one muscle group to recover while another is working.
3. Decide on the work time at each station (typically 30–60 seconds) and the rest time between stations (typically 15–30 seconds).
4. Decide on the number of circuits (laps of the full set of stations) — usually 2–3.
5. Include a warm-up before and a cool-down after the circuit.

Example General Fitness Circuit

Station	Exercise	Target Muscle Group / Fitness Component
1	Press-ups	Chest, triceps, shoulders (muscular endurance)
2	Shuttle runs	Legs (cardiovascular endurance, speed)
3	Sit-ups	Abdominals (muscular endurance)
4	Squat jumps	Quadriceps, glutes (power)
5	Tricep dips	Triceps (muscular endurance)
6	Star jumps	Full body (cardiovascular endurance)
7	Lunges	Quadriceps, hamstrings, glutes (muscular endurance)
8	Plank hold	Core (static strength)

Sport-Specific Circuits

Circuits can be designed to be sport-specific by incorporating skills and movements from the sport:

• Football circuit: dribbling through cones, heading practice, shuttle runs, passing accuracy, squat jumps.
• Netball circuit: chest passes against a wall, agility ladder, shooting practice, defensive slides, burpees.
• Swimming circuit: band pull-aparts, plank, squat jumps, shoulder presses, tricep dips.

Who Benefits

• Team sport players who need to develop multiple fitness components simultaneously.
• Beginners — circuits can be adapted to any fitness level by adjusting work time, rest time, and exercise difficulty.
• Athletes who want to avoid tedium — the variety of exercises keeps sessions interesting.
• Anyone with limited time — circuits are time-efficient as they develop multiple fitness components in one session.

Advantages and Disadvantages

Advantages	Disadvantages
Versatile — can be adapted for any sport, fitness level, or goal	May not develop any single component of fitness to a very high level
Develops multiple components of fitness in one session	Requires space and potentially equipment for multiple stations
Can be made sport-specific by including sport-related exercises	Needs careful planning to ensure muscle groups are alternated
Varied — reduces tedium	Can be less effective than specialised training methods for developing a specific component
Can be done with minimal equipment (bodyweight exercises)	Requires knowledge of correct technique for each exercise to prevent injury
Good for group training — multiple people can train simultaneously	Rest periods between stations may be too short for full recovery if developing strength

Exam Tip: If asked to design a circuit, always ensure that consecutive stations do not target the same muscle group. This is a common error that costs marks.

Weight Training

Definition

Weight training (also known as resistance training) involves using free weights (barbells, dumbbells) or resistance machines to overload the muscles. The specific way weights are used determines whether the training develops strength or muscular endurance.

Strength vs Endurance Training

The intensity (weight lifted as a percentage of one rep max) and the number of repetitions determine the training effect:

Goal	Weight (% of 1RM)	Repetitions	Sets	Rest Between Sets
Maximal strength	> 70% (heavy)	4–8	3–5	2–4 minutes
Muscular endurance	< 70% (lighter)	12–15	3	30–60 seconds
Power	50–70% (moderate)	3–6 (performed at speed)	3–5	2–3 minutes

Key Principles of Weight Training

• Progressive overload: gradually increase the weight, reps, or sets over time.
• Specificity: choose exercises that target the muscles used in the sport.
• Correct technique: essential for safety and effectiveness. Poor technique increases the risk of injury (especially back injuries).
• Rest between sets: allows the muscles to partially recover before the next set.
• Balanced programme: train all major muscle groups to avoid muscular imbalances.

Common Weight Training Exercises

Exercise	Primary Muscles	Movement
Bench press	Pectorals, triceps, deltoids	Lying on a bench, pushing a barbell upwards
Squat	Quadriceps, hamstrings, glutes	Standing with barbell on shoulders, bending knees to 90°
Deadlift	Hamstrings, glutes, lower back	Lifting a barbell from the floor to standing position
Bicep curl	Biceps	Holding dumbbells, curling the weight upward
Shoulder press	Deltoids, triceps	Pushing dumbbells or barbell overhead from shoulder height
Leg press	Quadriceps, hamstrings, glutes	Seated on a machine, pushing a platform away with the legs

Who Benefits

• Sprinters — strength training develops the power needed for explosive starts.
• Rugby players — need maximal strength for scrummaging and tackling.
• Rowers — need dynamic strength for repeated powerful strokes.
• Shot putters — need explosive strength to launch the shot.
• Any athlete looking to increase muscle mass, strength, or muscular endurance.

Advantages and Disadvantages

Advantages	Disadvantages
Highly specific — individual muscles can be targeted	Requires access to equipment (weights, machines)
Measurable — progress is easy to track (weight lifted, reps completed)	Risk of injury if technique is poor, especially with free weights
Can develop strength, power, or muscular endurance depending on the programme	Requires a spotter for safety when lifting heavy weights
Progressive overload is straightforward to apply (increase weight)	Can lead to muscle imbalances if programme is poorly designed
Increases bone density and joint stability	Not effective for improving cardiovascular endurance
Wide range of exercises available	Can be time-consuming when including warm-up, sets, rest, and cool-down

Safe Practice in Weight Training

• Always warm up before lifting weights.
• Use a spotter when performing heavy lifts (bench press, squat).
• Start with light weights and learn correct technique before increasing the load.
• Do not hold your breath (Valsalva manoeuvre) — this can dangerously increase blood pressure.
• Use collars on barbells to prevent weight plates from sliding off.
• Wear appropriate footwear with a flat, stable sole.
• Rest between sessions — allow at least 48 hours for muscle groups to recover before training them again.

Plyometric Training

Definition

Plyometric training involves explosive exercises that use rapid, powerful movements to develop power (a combination of strength and speed). The exercises work on the principle of the stretch-shortening cycle: a muscle is rapidly stretched (eccentric phase) and then immediately contracted (concentric phase), producing a more powerful contraction than a standard contraction alone.

The Stretch-Shortening Cycle

1. Eccentric phase (landing): the muscle is stretched as the body absorbs the impact. Energy is stored in the muscle.
2. Amortisation phase (transition): the brief moment between landing and taking off. This should be as short as possible to maximise the energy transferred.
3. Concentric phase (take-off): the muscle contracts explosively, releasing the stored energy and propelling the body upward or forward.

Common Plyometric Exercises

Exercise	Description	Target Muscles
Bounding	Exaggerated running strides covering maximum distance with each stride	Quadriceps, hamstrings, glutes, calves
Depth jumping	Stepping off a raised platform (30–80 cm), landing, and immediately jumping as high as possible	Quadriceps, glutes, calves
Box jumps	Jumping from the floor onto a raised platform (box)	Quadriceps, glutes, calves
Squat jumps	Performing a squat and then explosively jumping upward	Quadriceps, glutes
Tuck jumps	Jumping vertically and bringing the knees to the chest at the peak	Core, quadriceps, hip flexors
Clap press-ups	Performing a press-up and pushing off the ground hard enough to clap before landing	Pectorals, triceps, shoulders

Who Benefits

• High jumpers and long jumpers — need explosive leg power for take-off.
• Sprinters — need power for a fast start and drive phase.
• Volleyball and basketball players — need vertical jumping power for spiking and blocking/dunking.
• Martial artists — need explosive kicking power.
• Any athlete who needs to generate maximum force in minimum time.
