How a lock should train
Powerful, durable and fit for 80 minutes of collisions.
The short answer
A lock should build collision strength and power, and practise tackling and breakdown work. The drills that matter most are tackle technique on the bag, scrum body position.

Technical drills for a lock
Most of these need a partner or a session.
Tackle technique on the bag
TacklingNeeds a partnerSetup: A tackle bag or shield and a partner to hold it.
- 1. Approach in a low, balanced stance — chest over toes.
- 2. Cheek to cheek: head to the side, never across the front.
- 3. Wrap both arms, drive with the legs, finish on top.
Volume: 5 × 8 each shoulder
Coaching point: Eyes open, head behind. Every safe tackle starts with head position.
Make it harder: Add a moving bag carrier, then a light live carry.
Scrum body position
ContactNeeds a partnerSetup: A scrum machine or a strong partner with a shield.
- 1. Set with a flat back, hips below shoulders, shins vertical.
- 2. Bind tight, then drive on the call through the heels.
- 3. Hold the shape for 5 seconds — the position is the skill.
Volume: 6 × 5-second drives
Coaching point: Spine in line, chin off the chest. A bent back in a scrum is how necks get hurt.
Make it harder: Add a delayed call so you have to hold the set position longer.
