When it’s time to work out, you wouldn’t don decades-old sneakers or use equipment left over from Jack LaLane’s boyhood gym. So why keep bringing that bulky music player along?

www.riohome.com ), makers of the Rio MP3 player, developed the $300 PSA/Play 120 with Nike, which apparently is moving its quest for global domination beyond athletic apparel and Tiger Woods ads. PSA/Play’s expandable 64MB built-in memory plays two hours’ worth of MP3 and Windows Media (WMA) files, enough to accompany the most grueling workout. The digital-display remote makes choosing a playlist easy, even on-the-go. After all, those 30 minutes on the StairMaster are hard enough without your MP3 player weighing you down.
