re: Sudden decrease in strength (left side)

So I think I have it narrowed down to my left Tricep. Military/shoulder press feel pretty normal, except my left arm tends to struggle with the final lock out. Bench was still super weak this week. I noticed today when doing one arm tricep extensions, my left arm struggled to keep up with the right arm. Everything else feels great, squats, deadlift, etc.

Going to deload for the next week or 2 on bench, and just work with dumbbells for the time being.

Thanks again for all the feedback.
