Chris Kibble of Esher RFC & Whitgift school says to start your sessions with a game. In this clip Chris runs a game called "Drop touch" where the players run back to a line when they make a touch. This is good for fitness and creating wholes to attack
Whether you're introducing tackling to young players for the first time, or re-introducing it to senior players after a summer away, this is a great game to play to ease back into it.
It isolates the 1v1 tackle and puts emphasis on technique without the high speed impact of a full contact game.
Another conditioned game that will test your players' fitness.
This requires all defenders to perform a 'down-up' after each touch, before re-aligning.
As players become tired, more gaps will appear, testing the defence even more.
