All the exercises had elements that were familiar in terms of motion so they didn't feel to foreign to me, yet they all had a new dimension that challenged. Shoulders, core, glutes, hamstrings and other leg muscles are all part of a triathlete's aresenal so it was great to work them all out in a short, efficient time span. Furthermore, our whole bodies were being put through motion in 3 different planes: front-to-back (which is the most common dimension for runners and triathletes) as well as side-to-side and up-and-down (which are more neglected).
There's lots more great information and advice on Ignition Fitness' website; I'd encourage anyone to give this class a try.
Have you ever tried TRX?
