Quadriceps
The large group of four muscles on the front of the thigh that straighten the knee and power running, jumping and squatting.
Overview
The quadriceps — usually shortened to "quads" — are a group of four muscles on the front of the thigh. They run from the hip and thigh bone down to the kneecap and shin, and together they form one of the largest and most powerful muscle groups in the body.
Their main job is to straighten, or extend, the knee, which makes them central to walking, running, jumping and standing up from a seated or squatting position. One of the four also helps lift the thigh at the hip.
Good to know
- Among the largest and strongest muscle groups in the body
- Heavily used in any sport with running, jumping or squatting
- Commonly trained in balance with the hamstrings at the back of the thigh
Where it’s used
Sports this relates to:
Running
The most accessible endurance sport — no venue, just shoes and the open road or trail.
Cycling
A low-impact endurance sport that doubles as transport, exercise and adventure.
Football
The world’s most popular team sport — endless running, teamwork and community in one game.
Basketball
A fast, dynamic team sport of running, jumping and quick decisions on court.
Weightlifting
A technical strength sport built around lifting a loaded barbell overhead with speed and control.
Exercises that work the quadriceps
Squat
A foundational lower-body movement where you bend at the hips and knees to lower down and stand back up.
Goblet squat
A squat variation where you hold a single weight close to your chest for balance and control.
Jump squat
An explosive squat variation where you spring off the floor at the top of the movement.
Wall sit
A holding exercise where you sit against a wall with no chair, holding a squat position still.
Lunge
A single-leg movement where you step forward and bend both knees to lower your body.
Bulgarian split squat
A single-leg squat where the back foot is raised on a bench behind you.

Training methods
- Circuit TrainingCircuit training moves you through a series of stations back to back with little rest, blending strength and cardio into one time-efficient session.
- Strength TrainingStrength training uses resistance — bodyweight, bands or weights — to challenge your muscles so they gradually adapt and get stronger over time.
- Hypertrophy TrainingHypertrophy training is resistance work structured to encourage muscle growth, typically using moderate repetitions and a steady, controlled tempo.
- PlyometricsPlyometrics are jumping and bounding drills that train muscles to produce force quickly, developing power and springiness through explosive movement.
- Progressive OverloadProgressive overload is the principle of gradually increasing the demand you place on your body so it keeps adapting and improving over time.
Training plans
- Beginner Full-Body WeekA general example of a simple full-body week that spreads a push, a pull, a lower-body movement and some core evenly across three unhurried sessions.
- Walk-to-Jog PlanA gentle example of easing from walking into jogging by gradually mixing short, easy jogs into regular walks over several weeks.
- Beginner Strength WeekA general example week for someone learning the basic strength movements, built around a few short, technique-focused sessions with plenty of rest.
- Home Bodyweight WeekA general example week of short, equipment-free bodyweight sessions you can do at home, built from simple movements like squats, push-ups and planks.
- Beginner Cycling BaseA general example of building an easy aerobic base on the bike through mostly relaxed, conversational-pace rides over several weeks.
Training guides
- Bodyweight training basicsBodyweight training uses your own body as resistance, making it a simple and accessible way to build strength almost anywhere.
- How to start strength trainingStarting strength training means gradually introducing resistance movements and learning good form before doing anything more demanding.
Movement patterns
- GaitThe cyclic, alternating single-leg pattern of walking and running that carries the body across the ground — the base of most field and endurance sport.
- JumpThe plyometric pattern of projecting the body off the ground through explosive triple extension and controlling the landing — the core expression of lower-body power.
- SquatA knee-dominant pattern: bending the hips, knees and ankles to lower and rise while keeping the torso upright — the foundation of lower-body strength.
- LungeA split-stance, single-leg-emphasis pattern: stepping or dropping into a staggered stance and pushing back up to build single-leg strength, balance and stability.
- AccelerationThe athletic pattern of building speed from a standing or slow start by driving large horizontal forces into the ground to project the body forward.
Positions
- Power forwardThe power forward plays near the basket in basketball, using strength to rebound, score inside, and defend the paint.
- Point guardThe point guard is basketball’s primary ball-handler and playmaker, running the offence and setting up teammates to score.
- Defensive midfielderA defensive midfielder sits in front of the defence, breaking up opposition attacks and shielding the back line.
- HookerThe hooker is a front-row forward in rugby who wins the ball in the scrum and typically throws the ball into the line-out.
- Outside hitterThe outside hitter attacks from the left side of the net and is often a volleyball team’s main scoring option.
Facilities
- Sports hallA large indoor hall with multi-sport line markings, used for court sports like basketball, volleyball and badminton.
- Fitness studioAn open indoor room used for instructor-led group fitness classes such as yoga, aerobics and indoor cycling.
- Football pitchThe large rectangular grass or artificial-turf field on which football (soccer) is played, with a goal at each end.
- Ice rinkA sheet of prepared ice, usually rink-boarded with rounded corners, used for skating and ice sports.
