I do not really know if you have heard about this thing named TRX, for those who do not know what it is I will give you a summary.. TRX are a couple of exercices you could perform with the use of a belt hooked to a tube or anything tall enough for you. There is a gym near my hosue that is offering TRX classes but I do not rally know if I should pay for them, do you think it is worth it?
