Feeling absolutely sluggish while working out. As soon as I do one set I feel dizzy, tired and anxious. I’ve been using a cheststrap to monitor my heartrate and I thought it looked normal, what do you guys think ? The first one is from doing chest and biceps . The second one is from doing legs (like squats, etc. — but not even that heavy compared to what I was used to do).
A single set of 8 reps of 25lbs biceps curl will send my heart racing 160bpm, and on the brink of collapsing. I don’t understand how and where this is coming from. I’m well fed, I drink water, my sleep is decent — no idea what’s going on. Doctor says my ECG looked fine & my general examination turned out okay.
Any thoughts ?
