In this Portuguese instructional segment, the presenter (Speaker A) explains an adapted version of the machine chest fly (crucifixo máquina) that aligns the machine’s force vector with the upper chest muscle fibers. He advises keeping the movement amplitude moderate to avoid overstretching and notes that the exercise is useful for shortening the muscle. He emphasizes the importance of adjusting the bench height—typically setting it slightly lower than usual and fine‑tuning it up or down until the optimal position is found. The speaker also promotes his "Muscle 60D" training program, highlighting its exercise‑specific periodization that allegedly delivers more than a year’s worth of results in just two months, and provides a link for viewers to join. The overall tone is instructional with a promotional edge, conveying confidence in the technique and enthusiasm for the program.
