The development of a
shoulder impingement can be caused by a host of contributing factors as it
relates to strength training, many of them coming as a result of the poor
choices people make, whether they realize it or not.
As it relates to strength
training, an impingement can result from one, or more, of the following
variables: poor form/technique when lifting, selection of exercises that compromise
the subacromial space leading to impingement, poor sequencing of movements
during a workout, or imbalanced development caused by incomplete training programs
that fail to address individual structural imbalances.
