Instructions for use:

Step one：Warm up your shoulders and arms thoroughly before using the Power Twister by jogging or jumping rope for five minutes, then perform 20 repetitions of both arm circles and bear hugs. Perform three sets of each Power Twister exercise. The number of repetitions you should perform in each set depends on your current strength level and the level of resistance offered by the particular Power Twister. The resistance of the Power Twister varies but is fixed and cannot be adjusted. Perform the repetitions until fatigue.

Positive grip:

Both hands hold the ends of the arm strength device, using the wrists, small arms and large arm strength to bend the spring upward, bending in the middle of the two handles from the position of the two fists, in slowly back to release the power!

Inverted grip:

Hold both ends of the arm strength device with both hands, use the wrist, small arm and big arm to bend the spring down, bend from the position of the two fists to the middle of the two handles, and slowly release the force! The difficulty of this is greater than the positive grip, it is recommended that beginners practice the positive grip first after trying!

Finally：Integrate the power twister exercise at the end of your upper body or chest workout so that your chest and arms don't tire when you perform other exercises.
