"The application of variety will be influenced by a number of factors. During periods of specialization (e.g. immediately prior to the commencement of the competitive period), there may be less scope for variety. Alternatively, in the period furthest from the competitive phase (e.g. the general preparatory phase), you can implement greater variety. The key to the use of variety is to know when to apply the principle. Use of variety should not compromise continuity in training when attempting to develop specific qualities, and variety should be implemented before the athlete becomes bored, not after. "
