Walking down the catwalk takes courage, style, and a great set of legs.  Heidi is well aware of all of the requirements and takes a lot of pride into each of them.  Her workouts are frequent, intense, and very specific to her goals.  If you want to get lean, long legs like Heidi try her workout on for size.  Do each exercise 3 times to failure and perform 15 repetitions for each:

1.  Lunges
Purpose:

To develop the front of the thighs (Quadriceps) and the butt (Gluteus maximus).
Execution:
•    With both hands on your waist and feet together, take a big step forward with one leg keeping your head up and back straight.
•    After you have taken your step, bend both knees bringing your trailing leg close to the ground (Inhale) and your front leg to 90 degrees.
•    Make sure not to thrust too far forward by bringing your front leg over your front knee but instead, ensure your momentum is continued straight down thereby preventing injury to the knee.
•    From this lowered position, bring yourself back up (exhale) by extending both legs back to the starting position and then repeat the movement for the desired # of reps and then don’t forget to switch legs and repeat on the other side.

2.  Hip thrusts
Purpose:

Used to exercise the muscles of the butt (gluteal muscles), stomach (rectus abdominis), and lower back (spinal erectors).
Execution:
•    Start by sitting down on the ball.
•    Then transform your ball into a bench by walking forward slowly until the ball reaches between your shoulder blades.
•    Now slowly lower your butt to the floor without moving on the ball (inhale).
•    Then thrust your hips up to the ceiling until they reach parallel to the ground (exhale) and then repeat for the desired number of repetitions.

3. Calf raises:
Purpose:
To develop the overall mass of the calf muscle (Gastrocnemius and Soleus).
Execution:
•    Stand up straight with your feet together and rest your hand on a wall or chair for support.
•    From there press up onto the tippie toes (exhale) and hold for 1 second.
•    Slowly lower yourself back down to the starting position (inhale) and then repeat for the required number of repetitions.

4.  Adductor raise
Purpose:
To strengthen the muscles of the inner thigh (Adductor group)..
Execution:
•    Lie on your side and lean up on your elbow.
•    Place your top foot over your opposite knee.
•    Maintaining this position, raise your lower leg 3-6” off the ground (exhale) keeping it straight.
•    Repeat for the required number of repetitions and then switch with the other leg.
5. Abductor raise
Purpose:
To strengthen the muscles of the outer thigh (abductor group).
Execution:
•    Lay on your right side, resting your upper body weight on your elbow.
•    Using your hand for balance, lift your left leg upward as high as is comfortably possible (exhale).
•    Hold for 1 second and slowly lower to starting position (inhale).
•    Repeat for the recommended repetitions and then repeat with the other leg.
