What makes the Sunny Health & Fitness Magnetic Recumbent Bike SF-RB4708 bike unique?

This recumbent bike from Sunny Health and Fitness is fairly unique in that it gives a complete CROSS-TRAINING workout.  It is one of the very few bikes available that also has moving arm levers.

Users are able to work the upper body including the arms, chest and back.

The cycling action also helps tone the legs, thighs and butt.

In some ways, the SF-RB4708 is much like an elliptical trainer, without the requirement to be in a standing position or put loading on the back joints and muscles.

What are the benefits of the Sunny Health & Fitness Recumbent Bike?

There are major benefits in using a recumbent bike that has moveable arms:

  1. You will burn more calories!  As the effort of the workout is distributed between upper body and lower body, you usually are able to work harder without feeling as fatigued as you might on an exercise bike.  You could burn as much as 400 calories in a 30 minute session!
  2. You can tone up the arms, chest and back.  Very few exercise machines work as many muscles as this.
  3. Your legs won’t get so sore.  When the workout is shared with the upper body, it takes tension away from the legs.
  4. The seating position helps protect your back.  Using a recumbent bike is ideal for people who are concerned about protecting the joints, bones and muscles of the lower back, neck and shoulders.
  5. The seat and seat back are oversized to help support the hips and back during the exercise session and ensure maximum comfort.

What do users say?

“The motion of the bike is smooth and the controls work well, seat adjustment is easy. I’m 6’4″ and my wife is 5’8″ so we need to be able to set it for each of us. We’re both 69 yrs. old, and I’ve had a stroke and spinal fusion surgery, and it’s a good machine to get on, pedal, stretch and watch TV or read my kindle”

“On the recommendation of my doctor because of a medical condition affecting my muscles, I started using a recumbent bike ……… The arms that move with the pedals allow my leg muscles to still be getting the motion even when my arms are doing more of the pushing”

“Members of my family have used just the arms where they put their feet on the ground away from the pedals, and then also used just the pedals and kept their hands to their sides. My son especially likes to use the pedals without the arms so that he can pedal faster and for more miles for his workout. I personally need to use the arms and legs together as much as possible to help keep my muscles moving since I have a muscular condition. But it has worked all three ways for us”
