Final answer:
The Shoulder elevated 1-leg hip lift is a variation of the Shoulder Elevated 2-Leg Hip Lift exercise, offering increased intensity by reducing the base of support and focusing on unilateral strength.
Step-by-step explanation:
The exercise that is a variation of the Shoulder Elevated 2-Leg Hip Lift is C) Shoulder elevated 1-leg hip lift. This exercise shares a similar starting position and targets similar muscle groups, but increases the intensity by reducing the base of support. Like the 2-leg version, the 1-leg variation focuses on the gluteus maximus, hamstrings, and core stabilizers, but with a greater challenge to balance and unilateral strength. The 2-leg hip lift is a more fundamental exercise, whereas the elevated hip thrust involves a higher elevation for the shoulders, and the 1-leg hip lift doesn't specify shoulder elevation, which is a critical component of the Shoulder Elevated 2-Leg Hip Lift.
