I agree, the New Years crowd is tiresome, but ja, at least they disappear eventually.
Im not sure what happens in the morning, I have only ever been early (before 6am) ONCE, and I was still so fast asleep I barely noticed!
I have been around 9am on weekends, thats nice, its pretty much the same crowd as we get on week day evenings, between 5pm and 7pm. I know the gym is really busy at this hour, but, aside from Mondays, which is impossible, I kinda enjoy it. You know you're going to struggle for space and equipment, but it forces you to shake up your workout by finding something else to do while you wait. A lot of the guys are serious BB'ers, and the school boy/girl crowd leaves before 4pm. I have noticed the house-wifey perfume wearing crowd seems to go mid morning. Its nice to train at the same time every day, as you become 'part of the furniture' and eventually know everyone by name. We do chat, but mostly we're focussed and listening to our own music, everyone respects that we're all here to train, those who just come to chat dont gain many followers. The afternoon crowd is often maligned, but, its the only time we have, (or can cope with) and we like it.
The local mall and beach is also close, so we also see each other 'around', as far as I can tell, its a good bunch.
A lot of the guys who compete, do cardio in the mornings, so, I also think the serious morning trainers (cardio-wise) are actually also the same guys who train weights at night...
