Question: 1 / 400

Which exercise requires the greatest contribution from trunk stabilizers when using 80% of 1RM?

Barbell bent-over row

The barbell bent-over row indeed engages the trunk stabilizers significantly, particularly when using a heavy load like 80% of one’s one-repetition maximum (1RM). This exercise involves a forward-leaning position, which requires the activation of the core muscles, including the transverse abdominis, rectus abdominis, and oblique muscles, to maintain stability and support the spine throughout the movement.

In the bent-over row, as an individual pulls the barbell towards their torso, the trunk stabilizers must work hard to counterbalance the torque produced by the weight, preventing excessive bending or twisting of the spine. This stabilization is crucial to avoid injury and ensure proper form during the exercise.

While the deadlift, squat, and leg press also require core stability, they generally involve more linear or vertical movements that allow for greater overall body support and balance, relying more on large muscle groups and less on isolated trunk stabilization. The position and dynamic nature of the bent-over row particularly emphasize the role of trunk stabilizers in managing the heavy load while maintaining a proper posture.
