Proformance Plus PPL-970 Abdominal Crunch - The Proformance Plus Abdominal Crunch by TuffStuff takes the awkward to perform but highly effective weighted crunch and improves its function so that your focus can be on feeling each rep rather than on holding a heavy weight in place. The weighted crunch has long been recognized as one of the most effective exercises for toning and strengthening the entire abdominal wall but is also so uncomfortable that many avoid it. With free weights, your primary options are to hold a weight plate behind your head or rest a dumbbell or weight plate on your chest. Neither is ideal. Holding a plate behind your head creates the obvious hazard of pulling against the plate for leverage and straining your neck. Because the range of motion for the abdominal crunch is relatively short, many trainees can work up to handling fairly heavy poundages. Imagine the pressure of an 80- or 100-pound dumbbell bearing down on your chest and making breathing difficult while you lie on the floor and attempt to crunch. At this point, many abandon the crunch as part of their workout routine and forego all of the benefits this excellent exercise offers for building the upper abs, lower abs, and even the obliques.

The 9.5 weight horn on the Proformance Plus Plate-loaded Abdominal Crunch Machine allows you to load far more weight than you could ever tolerate comfortably with its free weight counterparts, yet you will be able to do so with the only discomfort coming from exactly where you want it: the deep burn of contracting your abdominal muscles repeatedly to move the load. Three points of rotation means you will not just be crunching your torso toward your knees as with a traditional crunch. You will also be lifting your knees toward your shoulders, creating a more intense contraction in the lower abdominal muscles and greatly improving the effectiveness of the exercise. The unique design of this machine permits users of different heights to begin without any adjustment to the seat or movement arms, while the five-position swivel seat enables them to hit the abs from different directions, more directly targeting the hard to reach intercostals and obliques for full core development.® is the EXCLUSIVE GSA Dealer for Tuff Stuff Fitness Proformance Plus and PRO-XL Sports Performance exercise equipment to the military and government.
