After that first video, I was told this skill and challenge needed to be more of a multi-joint movement, instead of the single-joint movements I was doing.
Today, I tried grooving the skill on a bar in a power rack and progressively lowering it.
The first clip shows the bar about an inch off the ground. The second clip, I swung the camera around best I could to show another angle. I also put my feet up on a mat to get it more in line with my hand.
Arms were a bit tired after all the attempts, so that's all for today. Taking a break from this for the next week in prep for a powerlifting contest.
