look like you need two ropes, this is actually one rope attached to an anchor. all the ropes will be long enough to be divided in half and still give you sufficient length to work with. working with more than one rope makes no sense. after all, you only have two arms, where would the rest of the ropes fit? if you are looking for more weight to keep you going, you can just buy a thicker rope since this will be enough to challenge you once more. or you could switch up your routine!
q: how long should my rope be?
the longer a rope is, the better it will be!
