Suspension training helped me launch my semi-private training business 3.5 years ago. I started out with TRX, which is a good product and they have good educational programs (I have their STC and Sports Med certificates and have taken many workshops at IDEA).
A year ago, I switched to CrossCore. I started with one CrossCore as a novelty just to add it into my circuit. Clients loved it so much, I completely switched over. It’s an improvement over TRX because there is a pulley at the top instead of the fixed anchor. This allows for unilateral movement, transverse plane rotation, and it converts easily to a cable machine. The handles also clip off and you can attach accessories like gymnastics rings, grapple grips, and bars.
I’ve also used the Rip60. Of the three products – CrossCore, TRX and Rip60, it’s my least favorite. Clunky feel, no adjustable footstraps, and the pull isn’t as smooth as the pulley feel of the CrossCore.
