The word "Zercher" refers to the location of the barbell during lifts – the crooks of the elbows – as in the popular Zercher squat. But the Zercher position can be used for many exercises, even the good morning.
In the traditional good morning, the bar is held on your back in the back squat position, but you can also use the Zercher hold and do a seated good morning.
Maintain a neutral pelvis and keep tension through the heels to strengthen the posterior chain. Or use this exercise as a warm-up just to open up the hips.
