I also agree with Jonathan and Christine. TRX will always be around and it will be an essential training because of its versatility and it’s easy to take it anywhere. It’s very light weight, it takes not space and can be set up pretty much anywhere. I know many guys in the military who love it and they swear by it. For these reasons alone TRX is here to stay :-).
I have been teaching TRX for a few years now and it has proven to be a useful format. I agree with Jonathan that it is functional and it applies to many different fitness levels, plus it’s easy to set up. In addition, it’s different, challenging, and fun.
I have seen great improvements in core strength in my clients and class participants with TRX–and I think it is here to stay.
If you mean Suspension Training in itself, then absolutely! It’s functional, portable and applicable to many different levels of fitness. Even if the company that makes TRX Suspension Trainers somehow doesn’t exist in the near or distant future, I believe there will always be a place for this kind of training tool.
