Exact-effing-ly...!
I'm sorry to harp on this, but it keeps happening to me and I've been dying to vent. I was working in my squats in a rack with a dude who kept edging closer behind me and "encouraging me" on doubles. I mis-timed a squat with a relatively easy weight because I saw him hovering behind me in the mirror. I let it go on the pins and told him with more than a little annoyance in my voice that having people too close makes me really nervous and prone to error. He said he just didn't want me to hurt myself! Ha! What he was really doing was over-compensating for the fact that we were the same size but my work sets were 100 lbs more. Eager Spotter, If I miss a rep, I will set it down on the pins. I will not get hurt. This isn't my first rodeo. But I'm glad to know this happens to jacked-looking lifters, too.
Anyway, just so it's not all about me complaining about Roving Squatters, I was hoping you'd mention any "neuroprotective" effects you may notice with the RAD.
