"She’s been a good influence": Alex Rodriguez credits girlfriend Jaclyn Cordeiro for keeping him in shape

The retired Yankee legend has been taking his health seriously and has reportedly shed around 30 pounds since last summer. In his latest interview with the New York Post, he credited his lifestyle change to his fitness instructor girlfriend, Jaclyn Cordeiro.

"She’s been a good influence with me," A-Rod said."I’ve been working hard and trying to stay in shape, and continuing to try to copy some of her great work ethic and health and wellness practices."

Further in the interview, A-Rod shed light on his fitness journey, talking about the changes he has adopted to keep his health in check.

"I’ve been training seven days a week," Rodriguez said. "I’ve eliminated a lot of the steak. I was a big steak eater. I used to eat steak probably eight out of 10 days, and now only one or two [days] out of 10 days. And then I do these 45-minute walks after dinner."

For the past eight months, Rodriguez has also adopted intermittent fasting to regulate his intake.

"I introduced intermittent fasting, maybe seven, eight months ago, and that’s been really helpful too, especially when traveling," he said. "You have to get a little bit more control of the things you’re intaking."

Alex Rodriguez feels Cordeiro's nursing background and transformation to lifestyle coach post-COVID-19 gives her a unique qualification to talk about fitness.
