At the end of the season manager Brian Laws said that he wants to keep the players fitness levels up over the close season.
After tomorrow's session the players will be handed a fitness target which they must meet at a later date in the summer.
If the player's do not meet these targets, then they will immediately be in for pre-season training ahead of their teammates.
“The players are professional athletes and need to look after themselves so we will be doing regular checks to make sure they do," said Laws.
