In need of some body inspiration (or eye candy)? Men's Health magazine has identified the "100 Fittest Men of All Time." Here are the top 10, starting with swimmer Michael Phelps. At 27, the Olympian has a record 22 medals.
2. Bruce Lee —
Actor and martial arts expert Bruce Lee was a big proponent of total fitness workouts that combined strength, cardiovascular, endurance and flexibility training. His methods are still used today in programs like P90X and Insanity.
3. Arnold Schwarzenegger —
Arnold Schwarzenegger wasn't always a politician. Here he poses during the 1977 Cannes Film Festival, where he presented "Pumping Iron," a documentary about body building.
4. Jack LaLanne —
Jack LaLanne is known to many as the "godfather of fitness." He spent decades promoting healthy eating and exercise. LaLanne died in 2011 at the age of 96.

7. Cristiano Ronaldo —
In 2008, Portugal's soccer star Cristiano Ronaldo was named the FIFA World Player of the Year. As a fan site states, "Ronaldo will take on any defender with searing pace, and mesmerising footwork to boot. His ability to beat a player and whip in crosses makes him a feared opponent."
8. Lance Armstrong —
Seven-time Tour de France winner Lance Armstrong may be the most controversial on Men Health's list. The cyclist has been up against doping allegations for years. This week, Armstrong lost his multimillion-dollar deal with Nike and stepped down as chairman of the Livestrong charity foundation.
