Recumbent - Would a dual 20" wheel setup be better for fitness?

I've read in more than one post that recumbents with dual 20" wheels take more effort to keep going. Because of this, would a dual 20" bent make a better choice if the goal is fitness?

Probably not that you would notice; I remember a fellow rider on a RANS rocket blew my doors off during an afternoon ride one time.

What does that link have to do with the orig. question?

Are you a person who doesn't care how fast you go or how long it takes to get there? I do. I have limited time to devote to cycling and need to get the most out of it. You can get the same amount of exercise from any recumbent but you may just have to ride a little faster or farther on a lighter, more efficient model. I traded up from a very inefficient, grossly heavy BikeE AT that discouraged the heck out of me when I first took up recumbent riding. After a few months I switched to an older Linear LWB which has the 20" X 27" wheelset. It still wasn't easy to ride as I hadn't ridden more than a few hundred miles a year (if that many) previously. I tried to ride every day and kept my level of effort the same as I got more fit by riding faster and choosing more difficult (i.e., hilly) routes. By the end of 11 months I had racked up 3,000 miles and could ride 30 to 40 miles without falling over exhausted. If I had kept riding the BikeE, I would have given up a long time ago. It just wasn't fun to ride an inefficient bike. Funny, I am back to riding a 20" wheel recumbent weighing 39 pounds (GS GTO trike) but it doesn't seem all that inefficient any more.

I think a Moulten bike set some sort of speed record on 17" tires?

20" wheels are harder to knock out of true than big, thin spoke racing wheels.

Squeaker...no offence intended.

I'm building a 20"x16" SWB just for the heck of it to see how it rides. If I don't like it my daughter will ride it. It'll be a HECK of a lot lighter than my LWB though.

If you're not getting enough of a workout with 26" or 700c wheels, then you're not pedalling hard enough. ;)

Lots of good comments. I'll add one more comment. The best fitness bike is one that you'll ride regularly, no matter what size wheels it has.
