Activation multifidus seated

Perform the described movement slowly and steadily while keeping the involved joints aligned. Complete the range without using momentum through the hardest portion. Prioritize control over speed. Maintain useful tension through the range and deliberately reset the starting position before the next repetition.

Do not turn the final repetitions into fast or partial movements. Aim to load lower back and spinal erectors without sacrificing position; at beginner level, progress control first and then add load, repetitions or complexity.
