how can you say they dont train for hypertrophy..... you cannot just walk up to a set of rings and begin practicing.
isnt what they do just another form of holding say a dumbell i parallel to the floor? IE a form of achieving hypertrophy just in an unconventional way?
doesnt time under tension encourage the muscle to grow?
i dont see why you have given them special attention, they are just getting to hypertrophy in an unconventional way, well unconventional to those who only think classical style training builds muscle
and could you expand a little bit on that preachers being a great exer..... i dont see why its great and the others arent. PM if you want.. to not derail this thread
