Exercising
Many writings talk about how Elvis exercised constantly. He practiced Racketball. He rode a stationary bike at Graceland. He practiced Karate.
Daily Tuning
Daily Tuning Your voice —–
Elvis said many times in interviews about what he was doing to maintain his voice. The first thing he quickly and instinctively would say was that he tuned his voice everyday. Which means he took around 45 minutes tuning his voice every day. That doesn't includ melody tuning. He would start melody vocalizing on the song "Lead Me, Guide Me." He played on the piano every song he sung.
