Pressure Plate (Training Aid)
Also known as: balance plate, weight-shift trainer
A pressure plate is a training aid that measures how a golfer's weight shifts across the feet during the swing. This gives direct feedback on pressure sequencing that is otherwise invisible without instrumentation.
A pressure plate is a portable sensor mat a golfer stands on that reports how their body weight is distributed between the trail and lead foot. This means and often heel-to-toe within each foot. This means at every point in the swing, typically displayed as a live graph or a simple percentage readout. Unlike full force-plate systems used in biomechanics labs, consumer pressure plates are designed for practical, real-time feedback rather than research-grade force measurement.
The most common use is diagnosing pressure-shift timing faults. This means a golfer who hangs back on the trail foot too long in the downswing, or one who lunges toward the target too early, can see the exact pattern on the screen rather than relying on feel. This is notoriously unreliable for weight distribution.
Because the device gives instant, objective feedback, it pairs well with simple drills. This means feeling pressure move to the lead heel to start the downswing, for example. This means turning an invisible internal sensation into a visible number the golfer can practice against.
Example
A golfer discovers on a pressure plate that 70% of their weight is still on the trail foot at impact, well outside the range associated with efficient ball-strikers, and uses the live readout to retrain the timing.
Common mistakes
- Fixating on hitting an ideal percentage number rather than the pattern of pressure movement over time, which matters more than any single static reading.
In SwingVantage Motion Lab
SwingVantage does not measure ground pressure directly, since that requires a physical sensor mat. It can, however, observe visible proxies for weight transfer from video. This means such as lateral hip movement and posture changes through the downswing. This means which correlate with. But do not replace, true pressure-plate data.

- Vertical Ground ForceVertical ground force is the downward-then-upward push a golfer generates against the ground during the downswing, measured on force plates as a multiple of body weight. It is one of the clearest physical contributors to clubhead speed.
- Pressure ShiftPressure shift is the movement of the center of pressure under the feet — measured by force plates — from trail to lead during the swing. Elite players shift pressure earlier and more decisively than amateurs.
- Weight TransferWeight transfer is the movement of the body's center of pressure from the trail side (backswing) to the lead side (downswing). A complete transfer through impact is a fundamental source of power and consistency.
- Early ExtensionEarly extension is thrusting the hips toward the ball during the downswing. This causes the golfer to stand up out of posture and forces compensations at impact.
