Muscles Involved: The transversus abdominis stabilizes the spine and pelvis, and then the iliopsoas flexes the hips with help from the tensor fasciae latae. The quadriceps also assist with hip flexion as they keep the knees straight. Next, the rectus abdominis fires to posteriorly tip the pelvis and flex the lumbar spine. Once the lower body is flexed, the latissimus dorsi fires to bring the arms into adduction, toward the body. Finally, the middle trapezius engages to retract the shoulder blades and create a stable platform to support the body in a basket position.

Common Errors: Shoulders closing too early. Because the legs are straight during this movement, there is more load on the core. That’s why it is more likely that the hip flexors will engage sooner or more than the abdominals, pulling the aerialist into lumbar extension and making the posterior pelvic tilt and lumbar flexion needed to complete the motion much more difficult.

Bent knees can indicate that the iliopsoas are not yet strong enough to lift the legs, or the spine is not adequately stabilized to support the movement.

Common Error Pike-Up: lumbar extension and anterior pelvic tilt due to inadequate core stability relative to the force exerted by the hip flexors
