Final answer:
In a high bar squat set up, the bar should be placed near the top, on the trapezius muscles just below the C7 vertebrae, which allows a more upright torso and effective force transfer.
Step-by-step explanation:
For the high bar squat set up, the bar should be placed b. near the top, on the trapezius muscles just below the C7 vertebrae. This is in contrast to the low bar squat, where the bar is placed further down the back, on the posterior deltoid shelf. In the high bar squat, the placement of the barbell allows for a more upright torso and requires greater mobility in the knees and ankles. This position targets the quadriceps to a greater extent and is commonly used by Olympic weightlifters. Proper bar placement is crucial for balance and effective force transfer during the lift.
