The Swippler GRF is designed for strength and conditioning where the individual uses the Ground Reaction Force (GRF) to power the rotational movement required for most sports. In particular, The Swippler GRF enables the individual to focus on the strength and movement required to power the rotational movement of the upper body through lower body strength.
It is well recognised that the ease and speed with which shoulders are rotated in bat/racket/club wielding sports are crucial to improving expertise in the sport. The Swippler GRF enables focused lower body motion to power shoulder rotation training for golf, cricket, hockey, baseball and tennis.
The Swippler GRF works by enabling a simple drag force to be presented which the individual exercises against by engaging the legs, hips and core muscles to accelerate the shoulders in a rotational movement. The design of The Swippler GRF allows the arm involvement to be minimised so that the main focus is on how the legs and the trunk of the body can deliver rotational acceleration to the shoulder motion.
One key aspect for accomplished golf, tennis, baseball and cricket players is their ability to be accelerating the shoulder motion through the impact area of the strike. This acceleration can be at low speed or high speed depending on the power required for the swing, but in all cases it is important that the shoulders “feel” as if they are increasing in speed as they move the arms and hands through the impact area of the strike. The role of the feet, legs, hips and core muscles are key to this movement and The Swippler GRF enables the individual to build both the coordinated strength and “feel” for achieving this. One overriding focus is to keep the neck and head muscles in a relaxed state. The mind instinctively wants to deploy all muscles it can and neck muscle engagement affects the optimal rotation of the shoulders.
