SETUP: Sit on a bench with a high incline, a heavy dumbbell in each hand. Keep good posture by pinning your shoulders back & puffing your chest out.
REP: Let your arms fully extend. Your palms should be facing out in front of you. Curl the weight out to the sides (see video), bringing your forearms up until they reach a vertical position, then lower under control.
TIP: Your forearms and the dumbbells should create a “T” shape at the end of the rep (hence the name!).
