Mines across the street from work, so I just walk over after work.
It’s always tough starting at a new gym, like you said, learning when’s the best time to go, who’s cool with working in, who’s not.
At my gym the machines are way outdated, I’d guess from the 80’s and horrendous to use, but the free weights are from around the same time and I like the old school dumbbells better than the new hex shaped ones. They did get new power racks, but I like the old school squat rack best, the old bars have a nice bend in them, perfect for squatting!
