So I just wanted to make note for myself:
The jv squat with deep breathing in the hole and exhale prior to concentric is a tremendous pain in the ass. Now while it doesn’t literally hurt my glutes, it is certainly testing their endurance, I really dislike all the time I spend in the hole at rock bottom. I also find the weights rather humbling, since I could lift more (not a ton more, but more) without the breathing technique. I guess it is illustrating a weakness that could use addressing. Plus the light weights let me squat every day trouble free.
Hopefully this will translate into my dead lift which had been stagnant at 455. I thought the 10k swinging program would assist my dead lift but it did not assist at all. I guess my lockout was never the problem. Prior to all the swinging I had done a good amount of sldl and that made a significant improvement in my dead lift, similar to swinging but different. I plan to use sldl during the six week dead lift phase of the 18 week protocol. Dan John recommends rack pulls but my commercial gym doesn’t really have a way to do that. I thought this would be a reasonable substitute considering my past success with them, and they’ll keep the hinge going.
