Forget the Nike + iPod kit, Life Fitness wants to make "iPod" synonymous with "workout."
Earlier today they announced a new line of equipment that features built-in iPod integration. Once an iPod is docked, users can control playback and watch video via the machine's built-in LCD. Also, headphones can be plugged directly into the equipment. You can expect to see these in stores towards the end of March.
So now you can't blame the weather for canceling your workout. Thanks a lot, Life Fitness.
