Sir Leonard Hutton Fitness Guidelines :
Each player is responsible for his own fitness
He must be well rested and must not over train in practice
He should exercise only very mildly on off days
He may swim, play tennis or golf in the early morning
He must stay out of the midday sun
1986 Edition Of The Lord Taverners Cricket Clinic :
To develop stamina run, skip or cycle 10 to 20 mins in season
To develop strength : push up, sit ups and swing the bat
To enhance mobility, wide stride sitting, toe touching and head and
shoulder circling
