Locks are usually selected for height and lifting ability rather than throwing, so the first step is acknowledging role clarity: lineout throwing is typically a hooker skill, while locks focus on timing, elevation, and coordination. At amateur levels or in situations where a lock must throw, training should therefore borrow principles from specialist hooker practice while recognising physical differences.
Technique and target-focused drills
Improving accuracy requires breaking the throw into repeatable components: grip, step and pivot, arm path, and release. Drill examples that emphasise these components start with short, focussed target throws to fixed points at varied heights. Work from static throws into a stepped approach that replicates match footwork, keeping a visible target for the receiver. Use progressive variability by changing distance and height, and introduce a moving target so the throw adapts to a jumper’s run. The coaching material from World Rugby Coach Education, World Rugby, underlines the importance of progressive overload in skill acquisition and recommends structured repetition with increasing contextual complexity.
Pressure, variability and transfer to match play
Accuracy under pressure is the practical test. Simulated match drills that include contested jumpers, noise, lifting timing and defensive interference prepare a lock to deliver when routines are disrupted. Incorporating fatigue sessions and quick decision scenarios improves resilience. Loughborough University research into motor learning and skill transfer led by Paul O'Donoghue, Loughborough University, highlights that task-specific practice with realistic constraints produces faster and more robust transfer to competition than isolated technical repetition alone. This matters especially in community and school rugby where role-switching is common and contextual practice accelerates competence.
Relevance, causes and consequences are straightforward: inaccurate throws cause lost possession, stalled attacking momentum and territorial disadvantage, and can increase risk during contested lineouts if timing fails. Culturally, clubs with limited specialist players must upskill non-hookers, so drills should be accessible with minimal equipment and emphasise safety in lifting and catching. Environmentally, windy or wet conditions demand specific practice to maintain accuracy under adverse conditions.
Focusing on biomechanics, repetition, and contextual practice gives the best return. For a lock who must throw, integrate forced-variation target work, match-like contest simulations, and progressive overload guided by established coaching resources to convert training gains into consistent lineout accuracy.
