Scientists can use two tools together - one that measures muscle electrical activity and another that takes wide ultrasound pictures - to see how specific parts of the chest muscle change right after working out.

Non-uniform excitation of pectoralis major induced by changes in bench press inclination leads to uneven variations in the cross-sectional area measured by panoramic ultrasonography

Cross-Sectional Study

Human

2022 Dec

The study used the exact method mentioned in the claim (surface EMG plus panoramic ultrasound) and showed it works - they could detect different amounts of swelling and thickening in the upper vs lower parts of the chest muscle after different types of bench press exercises.
