Didn't realise that - still learning my way round Uni stuff. So I guess the trick is to start with full needs bars and maybe a snapdragon within range, so they keep going for hours. I've used it in a family like that and the trainer maxed out body skill while the other one gained a lot of lower points. It's less boring than studying fitness from the Edumacation bookcase anyway.
The clients use the machines (well, almost only the treadmill, but I can live with that), but the option to be personal trainer only appears very rarely on the machines while a client is using them.
I agree. The option doesn't always come up for me when I'm expecting it to. But, like I said I'm still learning Uni and could be missing something blindingly obvious.
