De-jiggle upper and middle back, upper arms and abs with a one-arm dumbbell row
Stand with right foot forward, left foot back, knees bent as though walking. With weight in left hand, bend forward, hinging from your hips, back flat, supported by your right hand on right thigh. Let your left arm with weight hang down toward the floor. In one smooth motion, keeping abs pulled in, bring the weight to your hip. Do 10-15 reps, then switch sides and repeat.
Posture pointer: Don’t just move your arms up and down; use the back muscles below your shoulders to do the lifting.
