Resist-a-ball (exercise ball)
Resist-A-Ball Exercises - These exercises are just a few
of the many exercises possible with a Resist-a-ball.
Each of the following exercises has two to three intensity or complexity
variations. Level I variations are described first and are the easiest
to perform. When you're able to perform the Level I exercises with
control and proper postural alignment, then proceed to the Level
II and Level III variations.
TRUNK EXERCISES:
SUPINE TRUNK CURL - Primary Muscles Worked: Rectus
abdominus, internal and external obliques
Primary Stabilizers: Neck, hips, legs
Joint Action(s): Lumbar spinal flexion
Starting Position: Supine incline position with
arms crossed over the chest or fists placed at your temples.
Execution of Exercise: Slowly curl your trunk,
letting your shoulders and upper back lift off the ball. Return
slowly to starting position and neutral posture. If your neck becomes
fatigued, place one or both hands behind the head for support.
Technique and Cueing Tips: Curl your trunk by
pulling the bottom of your ribcage down toward your hips. Avoid
pulling on the head or neck. Return to neutral posture between each
repetition.
Intensity Variations, Level II: Begin in the supine
incline position as above. Walk your feet backward, letting the
ball roll down your back until it is centered under the lumbar spine.
Your trunk is now more parallel to the floor (supine with lumbar
support - base position). Either place your hands behind your head,
or place your fists at your temples for more neck stabilization.
Curl your trunk as described in Level I, then slowly return to starting
position. This exercise requires more abdominal strength, balance
and postural stabilization than the Level I variations.
PRONE TRUNK EXTENSION - Primary Muscles Worked:
Lumbar spinal extensor group.
Primary Stabilizers: Neck, obliques, hips
Joint Action(s): Lumbar spinal extension
Starting Position: Prone with trunk support. Your
arms are at your sides, or wrapped around the back of the ball.
Let your spine flex slightly so your trunk is rounded over the ball.
Execution of Exercise: Slowly extend the spine,
lifting your chest slightly off the ball until the spine is straight
or slightly extended. Return slowly to starting position.
Technique and Cueing Tips: Lift the chest using
the spinal extensors, rather than pushing the trunk up with your
arms. The neck should be in neutral position throughout the movement.
To help find and maintain neutral cervical position, place one fist
under your chin, and perform the exercise without lifting your chin
off the fist. Use control to avoid excessive hyperextension of the
lumbar and cervical spine.
Intensity Variations, Level II: Begin in the prone
position with trunk support. Either place your hands in front of
your forehead, or place fists at your temples for more neck stabilization.
The spine flexes slightly as your trunk rounds over the ball. Extend
the spine as described in Level I. This exercise requires more strength
and balance than the Level I variation.
Level III: Begin in the prone position with hip
support. Use any of the arm variations above. For additional challenge,
reach over your head, keeping the biceps close to your ears. The
spine flexes slightly as your trunk rounds over the ball. Extend
the spine as described in Level I. This exercise requires more strength
and balance than the Level I & Level II variation.
Abdominal Exercise
SUPINE OBLIQUE CURL - Primary Muscles Worked:
Rectus abdominus, external and internal obliques
Primary Stabilizers: Neck, hips, legs
Joint Action(s): Lumbar spinal flexion and rotation
Starting Position: Supine incline position with
arms crossed over the chest.
Execution of Exercise: Slowly curl your trunk,
pulling your ribcage down toward the hips. As you begin to curl,
rotate the right side of the upper body toward the left leg. Return
slowly to your starting position and neutral posture. Repeat this
exercise alternating sides, or perform multiple repetitions on each
side.
Technique and Cueing Tips: Initiate each repetition
of the exercise with a slight curl prior to beginning the rotation
action. As you curl and rotate, press your lower back into the ball
and pull the right side of your ribcage down toward your left thigh
(reverse this action when you perform the curl on the other side).
Return to neutral posture between each repetition.
SUPINE REVERSE TRUNK CURL- Primary Muscles Worked:
Rectus abdominus, external obliques
Primary Stabilizers: Arms, upper back, back of
the legs, hip flexors
Joint Action(s): Lumbar spinal flexion (emphasize
posterior pelvic tilt movement)
Starting Position: Supine heel grip with hands
resting on the floor at your sides. Hips are flexed to approximately
90 degrees.
Execution of Exercise: Grip the ball between the
backs of your thighs and heels. Tilt your pelvis until your hips
lift slightly off the floor. Slowly return to starting position
and neutral posture.
Technique and Cueing Tips: Avoid swinging the
legs or actively flexing the hips to initiate the pelvic tilt. Instead,
curl the pelvis using the abdominal muscles. When returning to starting
position, the knees should lower to a position directly above the
hips (about 90 degrees of hip flexion). When learning this exercise,
the hands may press down into the floor to assist and stabilize
the movement.
SIDE-LYING LATERAL FLEXION - Primary Muscles Worked:
Internal and external obliques, rectus abdominus, erector spinae,
quadratus lumborum
Primary Stabilizers: Neck, supporting hip and
leg
Joint Action(s): Lateral trunk flexion
Starting Position: Side lying position with bent
leg. Place the fist of your bottom arm at your temple, and lightly
rest the top arm on the front of the ball. Allow the trunk to lateraly
flex slightly and round over the ball.
Execution of Exercise: Laterally flex and lift
the trunk slowly, pulling the ribcage down toward the hip. Pause
at the top of the movement, and then slowly return to starting position.
Technique and Cueing Tips: Maintain neutral alignment
of the hips, not allowing the top hip to roll front or back. Avoid
laterally flexing the cervical spine or letting the head tip to
the side. Let the supporting arm assist with balance, but avoid
pushing the body up with the arm. As you laterally flex, press the
bottom hip and side of the torso into the ball for added stabilization.
Intensity Variations, Level II: Begin in a sidelying
position with bent leg. Place both fists at your temples, elbows
out to the sides. Laterally flex the spine as described in Level
I. Maintain neutral cervical alignment throughout the exercise.
This exercise requires more strength, balance and postural stabilization
than the Level I variation.
Level III: Begin in a side lying position with
extended legs. Scissor one leg slightly front and the other leg
slightly back for balance. Place your arms in either of the above
described positions. Laterally flex the spine as described in Level
I. Maintain neutral cervical alignment throughout the exercise.
Adjust the width of your scissored legs for comfort and to facilitate
balance. A narrower width is more challenging than a wide scissor.
This exercise requires more strength, balance and postural stabilization
than the Level I & Level II variation.
SUPINE HIP EXTENSION - Primary Muscles Worked:
Gluteus maximus, hamstrings
Primary Stabilizers: Spinal extensors, obliques,
hips, arms (when on floor at sides)
Joint Action(s): Hip extension.
Starting Position: Supine with elevated legs.
Hands are resting on the floor at your sides or crossed over your
chest. The ball is supported under flexed knees.
Execution of Exercise: Slowly extend your hips,
lifting them off the floor until they are fully extended. Pause
at the top of the movement, then slowly return to starting position.
Technique and Cueing Tips: Your weight is supported
across the shoulder area. Avoid pressing the cervical spine into
the floor. When learning this exercise, press your arms down against
the floor to assist with balance and stabilization. After becoming
more skilled, perform the exercise without using your arms. Maintain
neutral posture in the lumbar and cervical spine throughout. Avoid
pushing up with momentum or excessively arching your back.
Intensity Variations, Level II: Begin in the supine
position with elevated legs. The ball is supported under the calves.
Perform hip extension as described in Level I. Hands may be placed
on the floor, or crossed over the chest. Leg width may also vary,
with a narrower stance being more challenging. This exercise requires
more strength, balance and stabilization than the Level I variation.
Level III: Begin in the supine position with elevated
legs. The ball is supported under the feet. Perform hip extension
as described in Level I. Hands may be placed on the floor, or crossed
over the chest. Leg width may also vary, with a narrower stance
being more challenging. This exercise requires more strength, balance
and stabilization than the Level I & Level II variation.
PRONE OPPOSITION ARM/LEG RAISE - Primary Muscles
Worked: Spinal extensor group (isometrically), gluteus maximus,
hamstrings, deltoids
Primary Stabilizers: Neck, spinal extensor group,
supporting arm, supporting hip and leg
Joint Action(s): Hip extension, shoulder flexion
Starting Position: Prone with trunk support. Your
right leg is extended behind you, foot touching the floor. Your
left arm is reaching out in front of you, hand touching the floor.
The biceps should be close to your ear. Let your spine flex slightly
so your trunk is rounded over the ball.
Execution of Exercise: Lift the left arm and right
leg slowly at the same time, executing a full range of motion without
rotating the hips or shoulders. Pause at the top of the contraction,
and then slowly lower back down to starting position. Repeat this
exercise alternating sides, or perform multiple repetitions on each
side.
Technique and Cueing Tips: Avoid hyperextending
the cervical spine by keeping the head still during the movement.
Movement should be slow and controlled, avoiding momentum. Adjust
the width of the legs and arms slightly to facilitate balance, but
maintain proper alignment of the leg and hip, arm and shoulder.
ADVANCED PRONE TRUNK EXTENSION - Primary Muscles
Worked: Lumbar spinal extensor group
Primary Stabilizers: Neck, obliques, hips
Joint Action(s): Lumbar spinal extension
Starting Position: Begin in the prone position
with hip support. Your arms are over your head, with your biceps
close to your ears. Let your spine flex slightly so your trunk is
rounded over the ball.
Execution of Exercise: Slowly extend the spine,
lifting your chest slightly off the ball until the spine is straight
or slightly extended. Return slowly to starting position.
Technique: Lift the chest using the spinal extensors.
Use control to avoid excessive hyperextension of the lumbar and
cervical spine. The spine flexes slightly as your trunk rounds over
the ball. This exercise requires good strength and balance.
