My gym here in the UK has these computerised machines - your trainer programmes the weight you should lift, no of reps and sets and rest time into a computer, then you are given a 'key' which you plug into the machine and it says 'welcome amanda - begin exercise'. It's good to remind me of what weight to set it at and if I lose count. On the cardio machines it tells me how many calories I've burned according to my exact weight. It also records how many you do and gives you a record over time - it's pretty cool really. The only thing is that it KNOWS if you haven't done a full workout and says 'you have not finished your workout, are you sure you want to quit!'
JENNIFER - IMO they are cool but it's not worth joining a gym just for them - they are good but not THAT good!
