Hollywood star Arnold Schwarzenegger is reflecting on a particularly challenging time in his life when he had unplanned open heart surgery, and had only a matter of months to recover and be back to top form.

In a video posted recently to his YouTube channel as part of his health and fitness group, Arnold's Pump Club, the 76-year-old actor and bodybuilder recalled a frightening incident in early 2018 when he was supposed to undergo non-invasive heart surgery, reports etonline.
