i have been using the elliptical alot lately and really like it. I usually go for 40mins at 4mph which is a good jog. Last night I decided to try it out at the highest level of resistance and at a slower pace. I really liked the workout I got out of that better than the 40min workout. Albeit I cannot go 40 mins on the max setting but after 15-20 mins I was drippind with sweat. Question is is one of these better than the other or should I do a combo of them both. I usually do 4-5 days/week and I have lost 30lbs so far and looking to loose 20 more. Let me know. Thanks.
