Hi, I was wondering if spotter arms that sometimes you see on half racks or even on power racks are good enough for bench pressing without a spotter. Are they safe enough? I looked at several gyms around my area and there aren't any that are really lifting focused and have a proper power rack with the safety bars that attach at two ends. I don't actually lift heavy yet, less than 150lb so I'm think I'm OK for now, but I just wanted to see what other people think.
The gym I'm currently going to has these spotter arms: https://i.imgur.com/exFRy7Z.png
Edit: maybe this should have gone into a different sub-forum, I thought it was injury prevention related though. Maybe it belongs in equipment?
