We all know the Explorer is a heavy dude with excellent attributes(probably best in the business) however some simple settings may help. Start with the armrest and move to fit our particuliar physical arm makeup. Now pay attention to the lower rod( too short and back will hurt from bending and too long the arm will hurt from holding the weight) fine line so do experiment..Also the swingy thing and homade devices do help and even saw one fellow swing two hand while have a rope attached to the bottom of the coil and worked for him. Perhaps someday a lightweight Explorer will appear on the scene, but until it does a little experimentation will help..
