In the first part, Simone shows us how to sculpt trouble areas with the help of a resistance band.

Glutes and obliques: There are two parts to this exercise. Using a resistance band, lay down on your side, and hook the band around your top foot, holding the ends of the band down in front of you.

  • Part A: Kick out to the side, and bring the knee back toward the navel. Do 20 reps  
  • Part B: Kick directly behind you, then back into your navel. Do 20 reps

Hips, thighs, and buns: Lean onto your elbows with the resistance band wrapped one foot. Kick your foot out, and bring the knee back in toward the chest. Do 30 reps on each leg.
