Sylvester Stallone, known for his protective nature, went above and beyond to ensure the safety of his daughters, Sophia, 27, and Sistine, 25, when they moved to New York City. Prior to their relocation, Stallone took the initiative to hire Navy SEALs to provide his daughters with self-defense training.

In anticipation of the second season premiere of "The Family Stallone," the family's reality show, Sophia and Sistine spoke to the New York Post about their challenging experience. Sistine revealed that the self-defense training, which was filmed for the show, was edited to seem lighthearted, but in truth, it was an intense ordeal. Recounting the rigorous session, she described spending six hours in the woods enduring rigorous training from the Navy SEALs, acknowledging that despite the edited montage, they faced the full brunt of the training and found it incredibly demanding.

Sistine mentioned that she wasn't caught off guard by her dad's decision to arrange such training, as they had been accustomed to his military-style self-defense drills throughout their lives. Sophia concurred, recalling their daily 6 a.m. routine, which included consuming eggs with ketchup—an odd yet apparently effective combination that their father believed to be advantageous.

Sylvester Stallone's wife reflects on Florida move: 'There wasn't much left for me in California.'

Their upbringing involved a lot of physical activities like sit-ups, push-ups, pull-ups, and clean and jerks, alongside leisure activities like golfing, pool, and shot put.

"They made the perfect boys," Sistine joked. In a scene from "The Family Stallone," Navy SEALs trained Sistine and Sophia to chase a chicken, reminiscent of a scene from "Rocky II." Sylvester explained, "Chasing a chicken sounds like a fun game. You have to have speed, patience, agility, and understand that you're going to be beaten by something that weighs three pounds and has a beak."
