| Contrary to what history (and That '70s Show) may tell us, everything that happened during the 1970s wasn't a temporary lapse in taste and reason. Sure, there was spandex, the Bee Gees, Grease and the Muncho Potato Crisp, but there were also hip huggers (which, thankfully, have made a triumphant return), Isaac Hayes, Enter the Dragon and the popularization of fitness, specifically, circuit training. If you've always dismissed the latter as just more residue of the disco decade, you're missing out on an efficient and effective training strategy. |
