Barbell lifts to exercise your back

1. Hold the barbell with both hands near the hip joints, arms drooping naturally, chest raised and abdomen slightly bent, feet shoulder-width apart.

2. Sit your buttocks back, lean down, and slide the barbell down your thighs to near the knee joints. Pay attention to keeping your back straight.

3. Maintain the above posture, tighten your back and exert force, lift your elbows and pull up, pull the barbell to near the lower abdomen, and then return to the original position according to the original trajectory. 15-0 reps per group, do 3-4 groups.
