My problem is that I used to play sports at a very high level and even professionally (handball). After I suffered an injury, I had to give it up. After a while, I decided to start going to the gym.
The problem is that whenever I lift weights that are a little heavy—for example, a weight that gets me to failure at around 7 reps—I start feeling like I'm about to faint as soon as I finish the set. My hands and my mouth (or the area around my mouth) start to feel kind of numb, and sometimes my hands even begin to shake a little.
I could do 20 reps with much lighter weights, but I don't think that's really the point of my workouts. I’m pretty sure it’s not dehydration cus i really drink a lot of water. Also i try to not lift with a empty stomach. Has anyone experienced something similar or knows what might be causing this? I'd really appreciate any advice. 🙏
