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
