Hi Conor, It can often be difficult to perfect a line-out as they can often be tricky and rely on other people to ensure they are successful. As Sportplan we have a number of drills that can help you improve your line outs, whether you are the thrower, jumper or lifter. Take a look at this video drill which shows how to jump correctly: Best of luck, Sportplan Team
The most difficult portion is learning to keep your lower body absolutely stiff and straight as you go up. But it's critical to do so if the lifters are going to get you up correctly -- and anyway, letting a stray foot catch one of them in the testicles is certain to screw up the lift.
squat a bit, jump a bit into the tunnel, arms up, toes pointed. not as easy as it sounds. that is how i coach it.
