Imagine Dragons frontman Dan Reynolds is proud of his body transformation after struggling with health issues.

He wrote on Twitter: “I’ve spent a decade fighting an auto immune disease that inflamed my joints (AS). I now live pain free, am in full remission & am the healthiest I’ve ever been. I owe it to Brad Feinberg Correct diet, vitamins & exercise. I’ll share it all w u soon. It’s been life changing for me.”

The singer then posted before and after photos that really do show how a huge difference. He continued: “just a few months of changing my lifestyle/diet/exercise and have overcome 2 diseases (UC and AS) that have haunted me for 10 years. No more pain. Sorry for the corny exercise posts but when you live in pain for a decade and someone fixes your body it’s nothing short of a miracle.”
