Hey! I go for a few weeks to the gym and it makes me totally fun! Especially the elliptical machine, it did to me. Actually my stamina is not that good, but the elliptical machine I keep loose 30 minutes at level 8 from. For the other cardio machines (this bike, treadmill) I am usually after 5-10 min already messed up. How can it be that there is such as great differences? I find the elliptical machine movements and relative ... monotonous, difficult to explain.
