Other ways to exercise back muscles
Pull (wide legs) hard.
Exercise erector spinae, gluteus maximus and trapezius.
Matters needing attention
Raise your head slightly, keep a certain tension on your whole back during the movement, and don't bend over.
Action description
Spread your feet wider than your shoulders, bend your legs straight, hold the barbell with your hands shoulder height, and raise your head slightly. The gluteus maximus and biceps femoris contract hard, and lift the barbell along the leg until the body leans back, and the gluteus maximus reaches the position of "peak contraction" and slowly returns in reverse.
