Mark Vazzana, 63
Mark Vazzana, likewise, adopted a healthy lifestyle later in life. It wasn't until he was 45 years old that he decided to quit his 30-year smoking habit, join a gym, and start the Zone diet. While most people fear such massive change, his perspective was different: "I knew in order to quit smoking, I needed to change everything at the same time."
At 56, Vazzana realized he was having trouble maintaining the fitness he'd gained, and at the encouragement of a young couple, he decided to try CrossFit, "90 seconds in, I knew I had found the Holy Grail of fitness and have been progressing ever since."
While he's recently cut back on some of the heavier lifting in favor of more bodyweight-focused WODs (that's workout of the day, for the uninitiated), his typical routine consists of three CrossFit WODs per week, some sprinting, and five hours of yoga and gymnastics in his backyard. That adds up to roughly eight hours of training per week, which may sound like a lot, but for a bod like that? It's really not so bad.
