I've been working out for a little while, and just started keeping a log of what I do at the gym. The hardest part has been trying to figure out what to log under "exercise". Sometimes, the coach will give me a name while telling me what I have to do, but other times he will just go "now you do this", while doing the motion I'm supposed to do.
Is there a place I can look up names for exercises and their variations, so I can write a proper log with correct names?
