When I had my home gym, i'd just walk downstairs in my underwear, dirty white t-shirt and bare feet and just start lifting. Crank the music I liked and I was off. Very unencumbered lifting lifestyle.
But we moved, and I had to sell the equipment (couldn't change countries with it...too expensive). Now I train at a commercial gym. I don't like it as much, though having machines for variety does prevent the eventual boredom of lifting 6x/week. It's a nice change.
Now I have to wear shorts and a real t-shirt that doesn't have hot sauce stains on it. And my hair can't be a total rat's nest. On the plus side, there are attractive women there who wear yoga pants, which is always appreciated and was an unexpected perk.
