I've been using the elliptical machine consistently for the last few weeks, going back and forth between the two 45 minute programs it has - Weight Loss 5 and Aerobic 5. Aerobic 5 slowly steps up resistance 3,4,5,6,7,5 but does it 3 times. You'd think that Aerobic would be more difficult than Weight Loss (the programs go from Weight Loss 1-5 to Aerobic 1-5 to Performance 1-5), but both my wife and I dislike the WL5 as in the last 15 minutes it alternates resistance levels 5 and 6 (tops out at 10) for 10 minutes straight, which about kills you.
Or so I thought until I was reminded of Performance 1 today. While only being 30 minutes, the programs resistance ends with 5,7,5,8,5,9,5,10,5,9,5,8,5,7,5. Weight Loss 5 doesn't look so bad anymore.
Change is good. It hurts, but it's good.
