Concentration Grid is a web/mobile device app implementation of the mental skills exercise used by athletic coaches and sports performance/psychology professionals for student-athletes (typically with pen/paper and stopwatch) . Concentration Grid provides convenient gameplay/replay and records time/performance data and history (the app also integrates sharing of results on social media). Concentration grids of between 3 and 14 rows/columns can be generated – and used for training/practice, skills conditioning and intra-squad competition. (The mental focus grid exercise is particularly popular with baseball and softball coaches.) Concentration Grid provides a fun competitive challenge for students, athletes, coaches, trainers, teachers, parents – young and old. Challenge yourself.


imb_05ev17Concentration Grid is a web/mobile device implementation of the mental skills exercise that many winning coaches and sports performance/psychology professionals have used with student-athletes to develop/improve and practice focus and concentration.

The objective of Concentration Grid is to select in sequence each of the numbers in the (randomly generated) grid.  Performance is timed as the athlete completes the exercise.

The level of competitive challenge/fun can be varied by changing the size of the grid – by selecting the number of rows and columns.  Concentration grids (sometimes called mental focus grids) can be generated in sizes ranging from 3 to 14 columns/rows.   Smaller grids challenge dexterity and quickness; larger grids require sustained focus and attention to complete.

Make self-development a daily habit.

Challenge your student-athletes … challenge your teams … challenge yourself.
