Jack LaLanne is known as the godfather of fitness, but don't think he's the only person in his family leading the fitness revolution. Chris LaLanne, Jack's grand-nephew, is spreading the word about the importance of fitness, and whether it's because of his famous last name or the fact that he really knows what he's talking about, people are listening.

He's developed a perfect workout formula, and it's not that different from the kind of workout Jack himself would prescribe. Here are five workout tips:

• Jump rope. It's cheap, easy and effective.
• Mix it up. Routine and boredom will be a drain on your energy level.
• Stick to the basics: Push-ups, sit-ups, lunges and so on.
• Make it intense. It's better to do less reps of more weight than vice versa.
• Stretch before and after every workout.
