🤔 Why can some drummers blast at 220BPM while others max out before? Drummers who achieve higher speeds tend to activate their hip and trunk muscles less (gluteus medius / erector spinae / tensor fascia latae / rectus femoris). A tense upper body can create unnecessary stiffness, hindering foot speed. By keeping the hips, lower back, and trunk relaxed, drummers allow better energy transfer for faster, smoother strokes. Less tension = more fluid movement = higher speeds! 🔍 Our study found 3 key
