Move: Stand tall with abs contracted, feet together. Hold dumbbells, one in each hand, with arms hanging in front of body, palms facing thighs. Keep hands close to body, and lift dumbbells up to chest level―elbows should be about shoulder height.
Next, extend forearms out to sides until arms are fully lengthened―you’ll form the letter “T” with your body. Return dumbbells to chest, then lower to start position.
Repeat: 2 sets of 15 to 25 reps.
