A lot of great comments!
Disclaimer: I do work with Fitness Anywhere, the company that makes the TRX.
Cred: My wife is a huge Cathe enthusiast and has been working out to Cathe videos for about 3 years now (even before I was associated with Fitness Anywhere).
Just some additional information on the Differences between the TRX Home, Essentials, and Force.
All of the base systems are made of the same type of straps with the same functionality and quality. The Force is millitary specific (but can be used by anyone) in the fact that it is an army green color opposed to yellow. The Force also comes packaged with a 12 week exercise regimine that gets progressively more challanging. If you like taking bootcamps and pushing yourself, this is the way to go. It does require cardio exercise, which you can suppliment with Cathe Cardio.
My wife uses the TRX during her Cathe workout in place of resistance straps and to modify some of the upperbody exercises she's building up strength for (like push ups and pull ups).
Hope this helps
