I honestly don’t see why you’d need 4-8GB for gym use. 1GB is enough to give you a week’s worth of music for the gym. 1GB is usually about 250 songs, which is usually about 12-16 hours of music. I don’t know your training schedule, but even with 2 hour sessions/ 5x a week, you’ll still have hours of music unheard.
Personally, I think the Shuffle is the ideal choice for the gym. It gives you enough music for 1 week of trips to the gym. So, once a week you change your playlist(if you care to hear all new music…) It weighs nothing, takes up no room, clips to your shirt, it’s sturdy and best of all, it’s dirt cheap. You can get them used for $30-50.
Also, the battery life is ~24 hours, meaning you can keep it in your gym bag(or wallet… they are small enough), until you decide to change the playlists
I can understand wanting to select, specifically, what you are listening to. But, for me, using an iPod in the gym has always been more of a distraction than anything else. Pre-planning the playlists falls roughly into the same organizational smarts as pre-planning food, workouts, post-workouts, pre-workouts…etc.
I think we can all agree that “workout music” is almost a genre of its own. Whatever types of music you listen to or prefer, undoubtedly, you enjoy certain songs more than others for working out to. It is easy to make playlists of workout music, and then you don’t need to fiddle with the iPod while you’re at the gym.
just my thoughts. A lot of people are staunchly against shuffles because they don’t have a screen, but honestly, that’s their best feature, given what they do.
