This type of training is what we call Differential Learning (DL). Using DL for warm-ups is a highly effective strategy, as it “opens up” a player’s system degrees of freedom. It can also be an excellent tool for light training days, especially for recovery, helping players restore a wide range of movement solutions post-competition.
When performing DL activities, we want to encourage as much variability as possible. A shooter may shoot out of different stances (e.g., feet wide, feet narrow, staggered, one leg), with different release speeds, varying arc heights, etc. There are an endless number of ways to do this. As the shooter performs their DL tasks, they should continually change their range and location (even if this means taking one or two steps between every shot). The passer should also pass from different angles, from different locations, and with varying velocities and spins.
