I always imagined that an inverted rope climb would be completely upside down ie the thumbs would be pointing toward the ground. I've been watching videos on youtube and it seems to me like everyone does there inverted rope climbs as more of a rowing motion, with the blade of the hand pointing toward the ground.
Is there anyone who does rope climbs with their thumbs pointing towards the ground? I imagine it would be far more difficult, akin to a bicep curl rather than an inverted pullup.
