Sharper Image Isometric Strength Trainer

The Sharper Image Isometric Strength Trainer is an electronic measuring device for isometric exercise. It measures both the push and pull force of an isometric contraction. The IGRIP allows the user to time the length of the contraction from 6-20 seconds. The IGRIP is a versatile device that can be used for a variety of exercises, including:

• Push-ups
• Pull-ups
• Squats
• Lunges
• Planks
• Rows
• Curls

The IGRIP is easy to use. Simply turn it on and allow it to initialize to zero. Then, set the timer for the desired length of time and assume the exercise pose. Apply push or pull force and the timer will count down. At the end of the exercise, an audio tone will sound and the average force during the exercise will display for 3 seconds.
