my rugby learning

Malo E leilei my name is kelesi and throughout this term me and my
friends have been training for Rugby and i have been waiting to share
my rugby learning with you.

What we have been doing for rugby training is fitness. The fitness we
have been doing is the, Beep test, running up and down the courts and
twelve minutes of running around the field.

Secondly we have been doing contacts in our trainings. Also what we
have been doing for contacts is a game of rugby and ball skills that
inclued contacts. Contacts are when people defend each other by
tackling.

The activity we done was that people had to line up. 4 people in each
line have a ball and number 1 is the first player and the max number
is 4. If the coach calls out the number 1 then everyone puts their
ball down and run with number ones ball then the game turns into a
rugby game.
