How to Adjust the Cable Tension on a Bowflex Revolution

The Revolution is a new style of Bowflex home gym that doesn't use the power rod technology. The Revolution features the Bowflex SpiraFlex technology, which is a series of six interlocking plates with elastic straps attached to the inside of each plate. As you begin an exercise, the straps tighten around a central pivot point, creating resistance. Pulley cables with handles attach to the resistance mechanism. Over time, these cables may begin to loosen. Check that the cables are properly tensioned and if not, tighten them.

Pull the swing arm adjustment knob out. Set the swing arm in the highest position and release the adjustment knob to lock the arm in place.

Look at the clips at the end of the cable. If they hang down and aren't tight against the pulley, you need to tighten the cable.

Locate the tension knob on the side of the machine, below the SpiraFlex plates. Pull the knob and turn the pulley below the knob, clockwise. Watch the clip above you retract. Stop turning the tension knob when the clip touches the pulley. Release the tension knob.

Repeat steps one through three on the other cable.


According to Bowflex, the more you use your Revolution gym, the quicker the cables will loosen. Check the cables regularly and tighten as needed.

There is a tension knob on each side of the machine. Adjust each cable separately.
