This has happened to me recently. I've been practicing for several years, and I used to be fine. About half a month ago, I suddenly got a headache when I rowed the barbell to the last one, so I quickly rested for a week, but it still hurt when I went again. I feel the last stroke of blood rushing into my head. Every time you jog for 65,438+00 minutes to warm up, you always do two groups of warm-up with empty bars before doing the action. There is nothing in the middle that makes me hold my breath. Recently, I'm worried. I'm going to have a good rest for two months instead of going to the gym this year.
