Hi there,
I recently purchased a TRX, having had a Jungle Gym for some time, i have the version 2 JG. The big difference is really the build quality and as you have mentioned the structure of the work outs. The JG can be used for all the TRX workouts, there is no real problem there, and in some respects is more solid when used on a door frame due to the design, but for ease of use the TRX stands out, and it also has the footstraps as you know.
I prefer the TRX, but hate the door anchor. Looking at Brads video it looks like its the earlier JG, as the JG2 has wider webbing and and the handles are padded similiar to the TRX. If i had to choose, then it would be the TRX, as its looks better from a clients perspective ( we are using the TRX to rehab patients at our medical practice here in the north of Scotland), and is much easier to set up and has better structured work outs.
The problem from a consumers perspective here in the UK is that the JG2 is a quarter of the price of the TRX,and several of our patients have commented on that, but my reply is always if they can afford to purchase do so, and if not, look at the JG2, with them purchasing the TRX DVD's when they are ready to do so.
