A method and a device are disclosed for improving performance in sports where a swinging motion is needed. In some embodiments, a swing resistance device may be attached to or be built into elongated sport apparatus, such as racquets, clubs, bats, sticks, and the like, configured to resist a swinging motion of the sport apparatus by capturing air and utilizing a force of air resistance, similar to a parachute. The swing resistance device is generally attached to the elongated sport apparatus by coupling components that allow the swing resistance device to freely rotate around the effective longitudinal axis of the elongated sport apparatus. During a swing, air resistance creates dynamic forces that over time may improve swing power and path.
