I like the idea of putting the exercises in and seeing muscle coverage, that's really cool!

The biggest hurdle for weightlifting for me is the data entry. I usually just have a set routine I go through, and recording weight and achieved reps is what I need to do. I tried the generate feature here, and was presented with a very complex interface that I wasn't sure would streamline my weightlifting experience. I don't feel like I struggle with determining how much weight to lift each time; I just keep it simple: similar weight as last time but maybe increase by a single increment on the last few sets.
