Is Suspension Training Dangerous, or Just Suspenseful?

The beauty of suspension training, the New York Times tells us, is that you can’t help engaging your core to steady yourself. The ugly, the Times says, is that the instability of suspension straps can result
in injury, especially if you have a history of joint or back injuries,
or inadequate core strength.
Suspension workouts, which consist of either hanging the legs or leaning back
while gripping the straps and then performing a variety of moves, are the new stability ball, aimed at the core muscles that avoid the influence of so many exercises. In the last two years, it has entered the mainstream fitness market in a big way–actually two big ways, with either TRX and Inkaflexx straps. And while most experts consulted by the Times agree that suspension training can do wonders for many, Fabio Comana, a research scientist at the nonprofit American Council on
Exercise, worries and "that segment of the population that doesn’t have joint integrity and the ability
to stabilize their entire body.”  They may use the wrong muscles, he warns, aggravating their risk for injury. Read more about suspension training.
