Hey, no prob on the late reply, cause I ended up getting sick anyway. I ended up taking the only form of magnesium I had, which was some pepto bismol like tablets from the track med kit and then using a tennis ball and a golf ball to massage it. I used light pnf with a rope when I warmed up and that seemed to help.
The day before I did heavy RDL’s (3×2@335) for my activation session instead of cleans like I usually do. It stopped the spasms for the rest of that day. But they started up again the next day, so I used what I wrote above. I honestly think it helped quite a bit.
