it's been very good for a few reasons:
1) no loud/horrible music. One of the main reasons I quit my prior gym a few years ago
2) people aren't filming themselves everywhere. Also why I quit the last place.
3) not many steroid driven people staring at you. Another reason I quit the last place. There are loads of fit people at Retro but they get that not everyone is on the same levels, and most look natural, so it's motivating (to see realistic fit physiques)
4) good variety of machines. ex. last gym didn't have a hip thrust machine or glute kick-back machine and Retro has more varieties of bench presh/push machines so I can exercise with good form and don't need to rely on free weights
