Strength training is a primary factor in athletics and rehabilitation. Lower extremity strength training has traditionally consisted of free weights, biomechanically designed weight machines, or plyometrics. The Plyo Press is a new machine that is currently being utilized in the Frappier Acceleration Program for athletes. It is specifically designed for lower extremity strength training in combination with plyometrics. The principle behind its design is to build strength in the most effective way to enhance speed and dynamic activity without the stress to the low back or legs that is present with the use of free weights.
Because the Plyo Press …

An Electromyographic Study Of Trunk Muscle Activity During Exercise On The Fitness Plus Low Back Unit, Joel Anderson
Physical Therapy Scholarly Projects
Purpose: Fitness Plus, Inc. has developed a series of exercise machines for strengthening of the trunk musculature. Their Low Back Unit is claimed to target the rectus abdominus (RA), gluteus maximus (GM), biceps femoris (BF), and erector spinae (ES) muscles, but there is no research to solidify these claims. The purpose of this study was to describe the electromyographic (EMG) activity during the use of the Fitness Plus, Inc. Low Back Unit.
Methods: Fifteen healthy, males (ages 20-30) volunteered to participate in this study. Surface EMG was used to assess the muscle activity in four trunk and hip muscles. The …
