Carrie Underwood's Leg Circuit Will Work Every Inch of Your Lower Body

There's no sitting down when faced with a two-hour show in front of a sold-out arena, something Carrie Underwood knows all too well. To make sure she can give the best to her fans, Carrie turns to trainer Erin Oprea to keep her in shape. This leg workout is full of moves that Erin does with Carrie on the regular to help keep the country star's lower body in top shape. In fact, Erin tells us that there's not one inch of the leg that will go ignored when doing this circuit. As Carrie herself says you're guaranteed to feel the burn.

Once the body is warmed up, Erin suggests repeating the circuit three times.

  1. Squat down on your right leg, left toes just touching the floor for balance.

  3. Keep your right leg bent and return your left leg to starting position.
  4. Do 15 reps, then repeat on the other side.

Tip: Don't ever fully stand. The key is to keep the standing leg engaged and burning, says Erin.

  1. With a 10- to 25-pound weight in your hand, place the top of your left foot squarely on the stability ball, with your right foot a couple feet out in front, right knee slightly bent.
  2. Fall at your waist as you roll the ball backward with your left leg until your back is parallel to the ground, letting the weight hang straight down. Make sure not to reach with the weight; you don't want your back rounding at any time during the exercise.
  3. Squeeze your bottom as you roll the ball back to the starting position and raise your body upright, keeping your core engaged for stability.
  4. Repeat this move 10 to 15 times before switching sides.
