Recumbent bikes are great for everyone and a favorite
for non-runners. They offer a non-impact cardio workout on one of the
more compact cardio machines. Stationary bikes are recommended for severely
overweight people who need to avoid putting extra stress on knee or
ankle joints.

• single action upright models that work only the legs.
• dual action upright models that also include handles which are
  pumped back and forth for an additional upperbody workout.
• recumbent cycles with the pedals forward so that the exerciser
  sits back on the seat and pedals with the legs extended in front
  of the body rather than underneath the waist. This style puts increased
  emphasis on the muscles of the buttocks, the back of the legs and
  the hamstrings. They are also considered to be more comfortable
  and easier on the back due to the support they offer.

  requirements
