i think its a similer principle to raidar chest pulls ( hold in to the top af a door with both hands fill your chest up with air and pull down streaching your thorax (i could be wrong with the thorax thing)
arnie swor by them and it makes me chest feel bigger after doing them for week or so but i havent done them continuesly for long enuff to see if they really work
are there any exercies recomended for chest expantion? |
