Cable Zercher Squat
Some cable machines come with a long, straight bar with holes at both ends. You can attach this to both cables in a paired cable machine. The first time I saw one I tried to do back squats with it, but the cables pulled on the bar in a way that’s hard to stabilize, and I hated it. More recently I tried zerchers instead, and these I love. Get the bar in the crooks of your elbows, squat down, and stand up.
You can do these with a single cable as well, but unless you’re very small, you may find the full stack isn’t enough weight.
Attachment: double-ended straight bar
Cable position: both cables at the bottom
