#720 Ground-Up Mechanics: From Foot Stability to Pelvic Rotation

**Why Your Downswing Doesn’t Start at the Hips** “Turn your hips harder” is one of golf’s most common instructions. But pelvic rotation is not an isolated action. An efficient downswing is a ground-up chain reaction beginning with the feet, ankles and shins. Elite players often show a small “sink” during transition before aggressively rotating and extending. A key mechanism behind this is ankle dorsiflexion: the shin moves forward over the foot while the heel remains functionally connected to the ground. This creates **Triple Flexion:** **Ankle → Knee → Hip** The ankle flexes, the knee accepts load, and hip flexion helps maintain posture and space. Together, these movements allow the body to lower its center of mass and prepare the muscles to produce force. A useful downswing model is: **LOAD → SINK → BRAKE → ROTATE → RISE** First, pressure moves toward the lead side. The body then sinks through controlled flexion, allowing the quadriceps and glutes to absorb load eccentrically. Next, lateral momentum must be braked. A stable lead-side structure allows rotation to accelerate before the body rises through extension and vertical ground reaction force. The principle is simple: **Absorb before you explode.** The foot is equally important. Rather than balancing only on the balls of the feet, golfers benefit from a **Tripod Foot:** pressure distributed through the heel, first metatarsal and fifth metatarsal. During transition, the foot initially helps absorb force before becoming a more rigid lever approaching impact. This also helps explain **Early Extension.** The pelvis moving toward the ball may be a compensation rather than the original problem. Restricted ankle dorsiflexion, insufficient hip internal rotation, poor hip hinge or unstable pressure management can reduce the golfer’s ability to load, brake and rotate efficiently. Instead of simply telling a golfer to “stay down,” ask: **What prevents the body from rotating correctly?** With **WatchItGolf 3D analysis**, coaches can examine Pelvis Sway, Lift and Thrust and how they interact with the chest, arms and club. An early Pelvis Lift, for example, may indicate that extension is occurring before the loading phase has been completed. The functional chain becomes: **Foot → Ankle → Shin → Knee → Hip → Pelvis → Thorax → Arms → Club** The downswing therefore does not simply “start with the hips.” The pelvis depends on what happens beneath it. **Organize the ground, and the speed will follow.** - My Blog⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ - ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠The Explainer⁠⁠⁠⁠**⁠**⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ - ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.ecoach360.com⁠
