The forward finishing clenched fist roll is perhaps one of the hardest forward finishing roll to execute. A good progression to get to this roll is the Storm roll, the forward finish norsaq rolls, and then the forward finishing hand roll. I was delighted when I got this roll, you can tell from the end of the video. To be honest I currently am struggling with completing this roll reliably. I suspect this is related to needing to improve my flexibility to keep lower to the deck. It is worth noting that sometimes Greenlander’s wear mittens when rolling and that would certainly help a little with this roll. A bulky tuilik on your arm can also help. For once water resistance is definitely your friend
