Training devices such as spike trainer, batting tee, etc. can be useful. Auditory aids can also be used. Practice Design well planned practices that get maximum activity by all participants.

Longer practices may be productive for players who are in good condition, endurance sports, already learned skills, and when interest levels permit.
Excessive practice can be counterproductive.
New skills should be taught at beginning of session. Most drills should be as gamelike as possible.

Encourage a variety of activities in younger athletes rather than requiring them to concentrate on only one sport.
