Even after a super hard leg workout, the inside of the thigh muscles don’t show signs of lasting damage or fluid buildup — they look normal again by the next day.

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.

Even doing a ton of leg exercises doesn’t cause lasting muscle damage or fluid buildup — at least not in guys who’ve been lifting for years.

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.

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.
