Weight transfer
The shift of body weight through the base during a strike, throw, or kick to add power and control.
Definition
Weight transfer is the coordinated shift of the body's mass — typically from the back foot to the front foot, and from a coiled to an uncoiled position — as a player swings, throws, or kicks. Moving weight into and through the ball links the large muscles of the legs and hips to the arm or striking limb, so power comes from the ground up rather than from the arm alone. It underpins a tennis groundstroke, a golf swing, a cricket or baseball drive, and a football strike.
The sequence usually loads onto the back foot during the backswing, then transfers forward as the hips and torso rotate and the front foot braces, with the follow-through completing the shift. Poor or reversed weight transfer — hanging back or falling away — leaks power and accuracy. It is part of the kinetic chain and works together with stance, footwork, and follow-through.
Where you’ll hear “weight transfer”
Sports that use this term:
Tennis
A singles or doubles racquet sport that blends agility, strategy and stamina on court.
Golf
A precision target sport played across an outdoor course, blending skill, strategy and a long walk in the open air.
Cricket
A bat-and-ball team sport where sides take turns to bat and to bowl and field, scoring runs.
Baseball
A bat-and-ball team sport where two sides alternate between batting and fielding to score runs.
Boxing
A striking combat sport built on footwork, timing and conditioning, practised from fitness drills to controlled sparring.

Movement patterns
- KickA ballistic single-support leg swing that whips force from the plant foot through the hip and knee to strike or propel a ball or target with the foot, distinct from the weight-bearing steps of locomotion.
- RotationRotating the trunk to generate and transfer power through the body's kinetic chain, plus anti-rotation — resisting unwanted twist to keep the trunk stable.
- StrikeA ballistic, whole-body hitting action that channels ground-generated force through a proximal-to-distal kinetic chain to deliver momentum to a target via the hand, an implement or a body part at the moment of contact.
- 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.
- ThrowPropelling an object by releasing it from the hand, driven by a proximal-to-distal kinetic-chain sequence that summates speed from the legs through the trunk and arm to the release point.
Techniques
- Free ThrowAn unguarded basketball shot taken from the free-throw line, relying on a calm, repeatable routine rather than power.
- Standing ClimbA cycling technique for climbing out of the saddle, standing on the pedals to add power on steep gradients.
- Bodyweight SquatA foundational lower-body exercise that lowers the hips by bending the knees and hips, then stands back up, using only body weight.
- VolleyA shot played near the net by blocking the ball out of the air before it bounces, using a short, firm punch rather than a full swing.
- PlankA static core exercise that holds the body in a straight line supported on the forearms and toes.
Disciplines
- Breaking (Gyeokpa)Gyeokpa is taekwondo's breaking discipline, in which practitioners strike through boards or other objects to demonstrate accuracy, focus, and effective technique.
- ClassicClassic is the original cross-country technique, with skis kept parallel in set tracks and a striding kick-and-glide motion.
- CompoundCompound archery uses a bow with cams and cables that reduce the holding weight at full draw, and is typically shot with a release aid and a magnified sight.
- Slalom (Whitewater Gates)Slalom kayaking times paddlers through a sequence of hanging gates on whitewater, combining precise boat control with reading fast-moving current.
- BreaststrokeBreaststroke uses a simultaneous, symmetric arm sweep and a whip-like frog kick, with a distinct glide between strokes — technical, rhythmic and the slowest of the four strokes.
Skills
- ThrowingThe skill of propelling the ball accurately and with control using the arm.
- CatchingThe skill of cleanly securing a ball travelling through the air or off the ground.
- BlockingThe skill of using the hands or body to stop or slow an opponent’s attack.
- SpikingThe volleyball skill of jumping and striking the ball forcefully down into the opponent’s court.
- BreaststrokeA swimming stroke using a symmetrical arm sweep and a frog-like kick, with the head lifting to breathe.
Sports science
- The kinetic chainThe idea that the body’s segments work as a linked chain, passing force from the ground up through the hips, trunk and limbs.
- BiomechanicsThe study of how the body produces and controls movement — the mechanics behind every technique in sport.
- Motor controlHow the brain and nervous system organise the muscles to produce coordinated, controlled movement.
- Movement efficiencyHow economically the body performs a movement — achieving the goal with the least wasted effort.
- Force and powerThe difference between how much force the body can produce and how quickly it can produce it — the mechanics behind strength and explosiveness.
