Each Practice Plan is designed specifically to be age appropriate.
Age groups are designated in even years (i.e. U6, U8, U10, etc.) but the sessions are also appropriate for the odd year preceding the age group listed (e.g. U6 practice plans are appropriate for U5 players).
If you believe that your players need more or less challenge, feel free to try Practice Plans in an older or younger age group. But please understand that each Practice Plan has been developed to enhance the development of each player on your team.
