The reason the arms and legs bend rather that rotate is that the character is constructed that way.
You would have to modify (or recreate) the character so that it has additional sprites for the arms and legs.
Ex:
Rather than the one sprite for the LArm and LForearm bones that bends, you would have to have a separate LArm and LForearm sprites.
To see what will bend rather than rotate, take your character into Composer Mode and look at the Bones.
You will notice that there are no red "Pins" between the LArm and LForearm.
Rotation occurs around the red "Pins" otherwise there is "bending".
Export your character to a PSD editor. Look at the LArm layer under the RL_Image layer.
Note that it is a single sprite going between the shoulder pivot and the hand pivot.
You need to modify the character to have a separate sprite for the LArm and the LForearm rather than just one sprite from the shoulder to the hand.
The good thing is that once you modify/change your character you can just replace the existing one with your new one.
Most of the movements should be fine but some tweaking might be in order.
For the G3 character on the left (Red top) I modified it to have two (2) sprites for the left arm.
The character on the right (Blue top) is an unmodified G3 character.
Using the G3 elastic folks perform "Hi" motion for both you can see the difference in the left arm.
Where the one on the left (with 2 sprites for the arm) rotates, the one on the right with a single arm sprite bends.
