In this Portuguese‑language YouTube video, the presenter argues that the free (deep) squat is one of the oldest human movements, used by our ancestors for practical tasks such as picking up objects, building fires, and resting. He explains that the squat engages the entire lower‑body chain—quadriceps, glutes, hip extensors—as well as the spinal erectors and abdominal muscles, and it also enhances explosive power for jumping and running. The speaker warns that modern sedentary habits, especially prolonged sitting, shorten the posterior‑chain muscles and reduce deep‑squat capacity, leading to pain and injury. He urges viewers to incorporate full‑range squats into their training programs to maintain natural movement patterns and prevent musculoskeletal problems.
