You Should Feel This: Abs
Exercise Families: Trunk Extension
Equipment: Exercise Ball
Trainer: Ashley Steele
Lie on an exercise ball face down with your arms and legs extended.
Lift your chest off the ball by extending your spine while simultaneously lifting your right arm and left leg. Hold the up-position briefly, and return to the starting position.
Reverse the movement, lifting your chest off the ball, raising your left arm while simultaneously extending your right hip. Pause briefly, and return to the starting position.
Repeat the movement and continue alternating sides for the specified amount of time.
Alternating Opposites on an exercise ball challenges core stability while strengthening your spinal erectors and glute muscles.
