In this informal Portuguese monologue, the speaker explains the stiff (Romanian deadlift) exercise, detailing the muscle groups it targets—hamstrings (posterior thigh), glutes, and spinal erectors. He contrasts it with typical hamstring exercises that involve knee flexion, emphasizing that stiff works the posterior chain through hip movement. The speaker strongly recommends the stiff as a top, essential lift to include in any training program, using casual and coarse language throughout.
