Tennis Forehand Firepower - Swing from the Shoulder: *Knowledge from Home* (Tennis and the Coronavirus Lockdown)

via Imgflip

CHALLENGE: Getting a massive free-swinging stroke with loose grip, smooth backswing, natural wrist lag, maximum "contact-point" time with the ball, "feet-legs-hip-core-dominant shoulder-wrist-hand" all firing in sequence, with a full flowing follow thru (kinetic chain).

PROBLEM: It can't be forced. It can't be tight. It can't be "arm-y" (all-arm). It doesn't come naturally or intuitively or without training or without informed knowledge. 

ANSWER: Follow the science. After the Unit Turn, and Backswing and Body Load (with "full stretch" in the chest and side): Focus on the pulling the non-dominant shoulder and hitting with the dominant shoulder. This automatically fires the kinetic chain and pulls the body sequence: hips-core-dominant shoulder-arm-wrist-hand-butt-cap at ball. This maximizes the full ARM & SHOULDER WING SPAN and makes it work together with the hips firing and core rotation. 

SOURCE: "The primary source of power was the horizontal adduction torque, which was used to accelerate the arm in the transverse plane."
