Ball Bridge with Leg Extension
by Dr. Christopher Notley

Muscles used

• gluteals
• quadriceps
• hamstrings
• erector spinae (back muscles)

Start Position

• Upper back rest on ball
• Pelvic tilt
• Knees bent to 90 degrees

Finish Position

• Push hips straight up to the point that the body is straight
• Extend one leg straight, balancing on the other leg
• Hold this position
• Lower hips down back to start position

Common Errors

• Arching the back.
• Having the ball at the middle of the back in the finish position. It should stay on the upper back.
• Allowing the hip, on the free leg side, to drop
• Bending at the knees to return to the start position. Drop the hips down.

Progressions
