Dumbbell Ipsilateral Split Drop (Fast Eccentric)
Stand tall holding a dumbbell on the working side with the rear foot on an elevated bench, drop down into a rapid eccentric split squat ('punch-punch stick'), and drive back up. Key points: - Drop rapidly under control into deep knee flexion - Stick and brake the descent violently at the bottom - Drive back up to the starting position Common mistakes: Lowering slowly rather than using a fast eccentric drop.
