Felt dizziness in ny first day
I went to the gym for my very first day today and ended up having a bad energy crash and intense dizziness right after working out. I started with a quick warm-up and light dumbbell shoulder raises, but then jumped into heavy sets on the barbell bench press and the chest butterfly machine. Right after finishing, my eyes started closing on their own, my head was spinning, and my energy completely vanished. I had to pretend to be on a call just to leave, and driving back home was really tough because of the severe lightheadedness.
Before heading out, I ate 1.5 eggs, a banana, and drank a glass of milk. My main goal is to lose weight and build a solid body recmposition but I want to make sure my body doesn't suffer like this again.
Is this kind of sudden dizziness normal for a beginner on day one, or did my blood pressure and blood sugar just drop off a cliff? I would love to know what I should eat or drink before heading in, and how long before the workout, to keep my energy steady. Also, how should I structure a light, 35-minute routine for my first week so I can adapt safely without draining myself completely?
