When you do more sets, you feel it way more than your muscles or strength show it — your brain notices the effort before your body shows physical signs.

Doing 14 sets vs. 21 sets doesn’t make your muscles look any different on ultrasound—even though you lifted more total weight in the 21-set version.

Even after a brutal leg workout, your muscles don’t get damaged or leak fluid in a way that shows up on ultrasound the next day.

Checking your muscle size right after a workout won’t tell you how good your workout was — it’ll look normal by the next day no matter how hard you went.

No matter how many sets you do, your thigh muscles look the same on ultrasound before and up to three days after—so swelling isn’t worse with more work.
