Richard Simmons has been laid to rest in a private funeral

His brother Lenny told PEOPLE: "Our beloved Dicky was laid to rest this morning surrounded by only family and closest friends. We pray for your continued love and support during this very difficult time."

TMZ previously reported that Richard fell in his bathroom the night before he died. His housekeeper reportedly urged him to seek medical attention but he refused "because he just wanted to stay home for his birthday".

The outlet added that the housekeeper helped him back to bed but found him unresponsive on the floor the next morning.

He had reportedly been feeling dizzy before the fall.

Richard was pronounced dead at the scene.

Shortly after news of Richard's death broke, his brother Lenny insisted he didn't want people to be "sad" about his passing and would prefer his life to be "celebrated" instead.

He told PEOPLE: "I don't want people to be sad about my brother.

"I want them to remember him for the genuine joy and love he brought to people's lives. He truly cared about people. He called, wrote and emailed thousands of people throughout his career to offer help. So don't be sad. Celebrate his life.

"He was very excited about all of his upcoming ventures he was working on. We are in shock. Please respect the family at this difficult time."

The wellness expert's passing is being investigated by the LA Medical Examiner's Office, but the city's fire department believe it was due to natural causes.
