4.2 Adjusting Resistance
The Twister Arm Trainer offers adjustable resistance levels, typically ranging from 40-150 lbs (or 30-50 kg as per some models). To adjust the resistance, locate the adjustment mechanism, usually a pin or screw system. Lengthening the bar generally reduces resistance, while shortening it increases resistance. Ensure the chosen resistance level is securely locked before starting your workout.
The device offers three adjustable levels of spring resistance, allowing you to select an appropriate intensity for your training needs. This feature enhances exercises for the wrist, biceps, chest, and other muscle groups, contributing to overall muscle strength improvement.
