Which exercise should be AVOIDED in program design for a client with spondylolisthesis?

The semi-circle on the Reformer is an exercise that involves significant spinal flexion and requires a stable core and pelvis. For clients with spondylolisthesis, which is a condition characterized by the forward displacement of a vertebra, exercises that place excessive strain on the lumbar spine or encourage forward bending can exacerbate symptoms and lead to further injury. It is crucial to maintain spinal alignment and stability in such conditions, and exercises that demand flexion can compromise the integrity of the spine.

In this context, exercises that promote extension and stabilization of the spine, as well as those that minimize movement at the lumbar spine, would be more appropriate and safer for an individual with spondylolisthesis. The other options involve movements that can be modified or adapted to avoid excessive strain while still promoting core strength and stability. Thus, avoiding the semi-circle on the Reformer helps protect the client’s spine and supports a safer program design.
