I love the elliptical, I have been using one 6 days a week for over 3 weeks straight now and I really have to up the resistance from where I first started to get a good sweat going. I average about 400 calories burnt in 33 mins. - i started at 4 mins of 2 risistance and 4 mins of 8 resistance back and forcth for 30 mins - 3 weeks later i am doing 4 mins at 8 resistance and 4 mins at 10 resistance for 30 mins - try sticking to the ellipitcal you will see a big differance in just a few weekas
