For swimmers, proper body alignment is critical. Swimmers need to work with the water and the slightest misalignment can cause them to work against it. Much of a swimmer’s training, however, focuses on working the global muscles – or the outside musculature system. It does not work the inside 'stabilizing' system. This bilateral imbalance leaves a swimmer open to misalignments which make certain parts of the body work harder than they should. That can add seconds to a competitive time or – even worse – to a variety of tears, pulls or strains.
