At 83 years old, Robert De Niro remains physically active and continues to take on new acting challenges. The veteran actor, who recently appeared in The Whisper Man alongside Adam Scott, told BBC Radio 2 that he exercises daily. De Niro explained that his fitness routine involves training "ten days in a row," depending on his schedule, and emphasized that regularity is key to maintaining his physical condition. He trains three, five, six, or even ten days consecutively, adjusting based on his professional commitments. Since 2025, De Niro has been involved in several projects, playing a president in the series Zero Day, a mobster in The Alto Knights, and a soldier in Tin Soldier. He is set to star in Shutout, a film directed by David O. Russell, alongside Jenna Ortega, who is known for her role in Wednesday. It is likely that De Niro has been engaging in intensive training to prepare for these diverse roles. Unlike Clint Eastwood, who often relies on weight training, De Niro prefers martial arts to stay in shape. He specifically practices tai-chi, a Chinese martial art known for its slow, deliberate movements and focus on balance and flexibility. This practice helps him prepare for physically demanding roles and endure long filming schedules. De Niro is also set to reprise his role as Jack Byrnes in My Father-in-Law, My Daughter-in-Law and Me, which is scheduled for release next December. The actor, who will turn 84 in 2025, has been in the film industry for over 61 years. With his continued presence in new projects, it appears he may be moving toward exploring more roles in martial arts cinema.
