"Looking at past records in the book gives you an idea of what has already been attempted," advises Janela. The website is also a great resource for finding milestones you might be able to pass. Either way, knowing what has already been achieved allows you to settle on an existing path or confirm that the path you've chosen is completely new. The most common attempts for individuals tend to involve at-home fitness, such as the most miles lunging or push-ups with a 20-lb pack on the back. Larger groups like schools and churches tend to target mass participation events, such as the largest assembly of people dressed as superheroes or simultaneously jump roping.
