"✅50 days 5am ✅ Getting in the best shape of my life," the star wrote. "Both physically & mentally. 1st photo 185 lbs 8% fat. 2nd was 6 months ago. 163 lbs 13%."

"We had 413 people finish the challenge. Pretty wild. Some of the results were amazing. Found a Sense of purpose. Increased energy. Better sleeping habits," he continued. "Some Lost 15-30 lbs. People ate better throughout the day. More productive at work. Found time for extra activities."

Continuing to explain his workout regimen, Schwarzenegger then detailed three main reasons why the 5 a.m. challenge has been effective for him.

"1. starts your day with a form of 'success' & builds momentum for the rest of your day," he said. "2. Shows your mind/body your capable of doing something you don't want to."

Schwarzenegger added, "3. Allows you to form small morning rituals/habits that lead to big results over time."
