The move targets core, arms, butt, legs and shoulders. Do 2-4 sets of 8-12 reps, 2-3 times a week, to get firmer in just under a month.
1. Stand with feet shoulder-width apart, toes facing forward. Hold a 5lb – 8lb dumbbell in each hand at shoulder height, palms facing in. With weight on heels, slowly bend knees and push hips back, lowering until knees reach 90 degrees (keep them behind toes).
2. Push back up through your heels while twisting your body to the right and pressing weights overhead until arms are fully extended. Make sure the twist comes from your core. Return to squat and repeat twist and press, this time twisting to the left. This is 1 rep.
