Even after a super hard leg workout, your thighs don’t stay swollen for days—the puffiness goes away by the next day.

Even after a really hard leg workout, guys’ thighs don’t stay swollen for more than a day — they go back to normal by the next day.

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.

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.

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.

When people who already lift weights do drop sets or rest-pause sets instead of regular sets—while doing the same total amount of work—they don’t get bigger thigh muscles any faster or more than with normal training.
