I've been doing starting strength for a couple of weeks now and have a friend who has been training me in the technique and spotting me on the bench press. This last training session he didn't pitch up.
While I'm confident that my technique is good enough to train on my own, I wasn't so sure about benching without a spotter and didn't really know if it's OK to ask someone randomly in the vicinity to give me a hand. Yesterday I asked one of the gym staff and they organised someone to give me a hand, but it brought up the question:
Is it ok to just randomly ask someone to spot me and how do I go about it?
