Ok, I've played rugby league for 4 years,I played the first season centre,the next 2 seasons stand off, and the last season full-back, I have done a fine job as I can catch the ball from kicks easy,but I realised the main job of full back is tackling, I normally get assist of the wingers, I want to improve my individual tackling so I can do 1 on 1's myself, I play for my school,and I play for a team who have a highish reputation, thanks.Ok, I've played rugby league for 4 years,I played the first season centre,the next 2 seasons stand off, and the last season full-back, I have done a fine job as I can catch the ball from kicks easy,but I realised the main job of full back is tackling, I normally get assist of the wingers, I want to improve my individual tackling so I can do 1 on 1's myself, I play for my school,and I play for a team who have a highish reputation, thanks.

To tackle, you must hit low and fast. Hit with your shoulder, NOT YOUR HEAD and hit them at their hip with your shoulder, but lock your hands around the back of their lower leg so that when you push with your shoulder they fall over. This is because you heighten their center of mass, meaning it is easier to knock them over with a smaller amount of force. So you conserve your energy for another tackle, meaning you will have less difficulty defending your line. Good luck mate and have fun.
