So, I have another question for those with all the knowledge in here (NoWorries, Azure, etc.). I saw a trainer on TV who was pretty negative towards elliptical trainers because the movement doesn't have 'application in real life' like a treadmill, stairs, and bike exercise would have. Would you agree that cardio on the elliptical is not as "good" because you never do those motions in real life? And this leads to my second question: my friend took me to a high-intensity aerobics class at GoodLife yesterday. It was definitely an intense cardio workout, but again, the movements in there don't have a lot of "real life" applications (unless you like to clap and bounce around a lot I guess

). So is it a "worse" workout to be doing aerobics when I could be doing a spin class/running stairs/jogging for an hour instead?
