5. Seated Twist With Shoulder Press
Targets: Abdominals, obliques, shoulders
How to: Start seated with your knees slightly bent (holding a dumbbell or weight is optional). Lean back slightly so your core is engaged. Keep your core tight as you touch the floor on your left and then twist to the right as you raise your arms above your head until they’re are extended completely. Lower your hands back to the floor on your left by reversing the twist and repeat the movement for 8 to 12 reps on the left followed immediately by 8 to 12 reps on the right.
