5. Static-Lunge Twist
Targets shoulders, abs, butt, and legs
Stand with right foot on step, knee slightly bent, and left leg extended behind you, as you hold dumbbells with arms extended forward at shoulder level, palms facing each other and knuckles touching.
Lower into a lunge, bending both knees 90 degrees, then twist torso toward right, lowering weights to outside of right hip.
Twist torso to center, bringing arms in front of you, then straighten legs to return to start.
Repeat, this time twisting torso to left and lowering weights by left hip.
Do 10 reps, alternating sides. Switch legs and repeat.
