The line-out is a crucial part of modern rugby and matches can be won or lost on how a side performs at the throw-in.
Most teams have their two main target men - the "jumpers", usually the second rowers - to aim for in the line-out.
Their job is to catch the ball from the hooker's throw-in and hand possession over to the scrum-half.
Create a comfortable base to jump from.
Listen out to the call from the hooker or scrum-half - most teams will have practised set moves on the training field.
Most of the momentum for the jump will come from your knees.
So as the ball is released, coil your legs and prepare to jump, using your arms for extra power will also help get them in position above your head ready for the catch.
Keep your eye on the ball and jump.
If you are 16 or over, you are then allowed to be supported by your team-mates.
Keeping your eye on the ball, catch the ball in your hands.
Both teams should have a one-metre gap between them before lift-off and players are not allowed to push, charge or hold an opponent.
But that doesn't mean there isn't often a lot of bumping and barging!
So make sure you have full control of the ball before you make your way down to ground.
Get ready to make the ball available for the scrum-half to collect.
Turn your back to the opposition as soon as your feet touch the ground.
This creates a wall, preventing the opposition from getting their hands on the ball.
Make the ball available for your scrum-half.
