100 Years of Fitness… In 100 Seconds

Trends come and go in most areas of our lives-- from clothes, to hairstyles and even cars. But what about fitness trends? They come and go, too. (Anybody still have their Thigh Master?) How many of these trends to you remember?

I'm thinking that all the current tough-mudder 5K-type races (like of like our own Insane Inflatables 5K) might be a trend that we'll one day look back on fondly, once it's replaced by something else. What that next thing might be, though, is anyone's guess!
