I've been doing 30 minutes on an exercise bike twice a week, for supplemental aerobic conditioning,
and also to help strengthen my quads as I've had knee problems. The club has two kinds of
bikes...the traditional upright model, and a model that is reclined as if you're leaning back in an
easy chair. I genrally prefer the traditional model, but I was curious if one or the other was
superior for quad strengthening. Does the position effect which muscles are utilized?

The recumbant cycle is better if you have a sore backside. Like from thinking too much.

p.b.s. rock with Elton John.On t.v. now doing the chubby checker twist . and leg lifts. My point is
a black and blue on thighs. now if this was a rip from long strand of pop and knot from 2002.
well could be the butt brain thing as miss thorpe said of. sort of. maybe tape the top of
knee cap in my case. then I do a little more biking then 2 times a week. inside biking would
seem to be so. ...."fake"!. (Fact of fake?) please explain!!! Like I think of Miss thrope.

N.S.to S.N. mag field space. were you are going. Then again. "she is a man!". Your Question
would relate to something to do with the calfs. Like standing and sitting calf exercises.
Helps one sitting bike to endurance this area in Question. calfs takes a licking and keeps on
ticking. done with heel on step for sore quad/ thights or toe/ball for not.
speed/endurance/'strength/ 3 out of 4. The 4th I would tell you, butt then I would have to
kill you.Please explain this Kill you 4. The twist.(twist is a 1960 yes dance step done with
a towel or without one.)
4. isn't the twist. just a dance break. since you in a gym most likely. you must know of the lower
and upper calfs. Bruce Lee (kung fu fighter) could bounce and stretch) this be 4. grasshopper.
Be one with the t.v. screan. As you well should know , Biking is done on one day a week. the
rest is used fo running.

> Does the position effect which muscles are utilized?

You will use your back a lot more if you are sitting in a flexed position. To test this, ride a real
bicycle: (a) sitting in the saddle; and (b) standing fully upright in the pedals (as in riding a
steep climb). When you are bent at the hip you can use your back to "straighten" that flex, which is
a contributing force to spinning in the pedals. Of coure, on a real bike, your arms also come into
play more when you are standing on the pedals.
