It’s not easy to overhaul your exercise routine, diet, and overall lifestyle, but Dan Reynolds has done just that.
The Imagine Dragons singer recently posted a series of tweets and Instagram photos sharing how he has treated his autoimmune disease and is now living a healthier life.
In one Instagram photo of himself, the singer thanked his trainer, Ben Feinberg. He wrote, “I’ve spent a decade fighting an auto immune disease that inflamed all my joints (AS). I now live pain free, am in full remission and am the healthiest I’ve ever been. I owe it to this man @thor345622. Correct diet, vitamins and exercise. I’ll share it all with you soon. It’s been life changing for me.”
Reynolds first opened up about his battle with ankylosing spondylitis, or A.S., during an Imagine Dragons concert in November 2015. The autoimmune disease is a type of arthritis that causes severe inflammation of joints in the spine, pelvis, and hips. According to the Mayo Clinic, it can cause some of the vertebrae in the spine to fuse.
Reynolds also has ulcerative colitis, a chronic disease of the large intestine.
As E! News reports, Reynolds later posted a before and after picture of himself on Instagram. “Sorry for the corny exercise post but truly changed my life and healed years of pain.”
The singer has been working on his health for a while. In 2017, he spoke to People about how he was dealing with A.S.
“It really has been a very healthy year for me. But it didn’t come without work, a lot of physical and mental work,” he told the magazine. “A.S. requires you to live a more disciplined life, and once I found the right balance of that I’ve really been great for a year.”
While Reynolds didn’t share exactly what he did to achieve such amazing results, the Spondylitis Association of America recommends daily exercise and a balanced diet with plenty of vegetables, fruits, and whole grains to alleviate symptoms.
