I’ve been trying different setups and nothing seems to work properly:
-narrow vs wide hands placement on the bar;
-full grip vs thumbless grip;
-very high vs high vs low bar placement on the back;
-elbows pointing down vs slightly back;
regardless of how I set up, after some time (less than a minute on average) I start feeling a tingly sensation in my elbows and wrists, with a quick numbness in the forearm, then the tingly sensation turns into discomfort and pain.
I’ve almost always done front squats with no issues, I can keep the bar front racked with full (close) grip on it and without elbows dropping down. Doesn’t hurt in the least wrists or elbows. Today I did a 2x front squats at 106kg, then wanted to practice a bit back squats but couldn’t do them with 70kg for more than 4-5 reps at a time - barely feeling any work on the muscles, had to stop every time due to the pain.
My only guess left is that I bench (close grip, hands shoulder width) the day before squatting, so I end up after bench and front squats with weakened wrists and elbows, but it’s really a shot in the dark.
