Stability Ball Knee Tucks

5 out of 5 stars
(12 Comments & Ratings)

Target Body Part: Abs, Legs - Calves and Shins
Primary Muscles: Rectus Abdominus (abs), Transverse Abdominus, Quadriceps (quads), Obliques
Secondary Muscles:
(Synergists/Stabilizers)
Erector Spinae, Anterior and Medial Deltoids (delts), Triceps, Pectorals (pecs), Serratus Anterior, Gluteus Maximus (glutes), Gluteus Medius/Minimus (Abductors), Adductors
Equipment Needed: Stability Ball

Step 1

Starting Position:

Begin in an all-fours position with your torso on the ball and hands and feet on the floor. Lengthen your legs and stretch your heels to the back of the room. Your hands should be under your shoulders.

Take a few deep breaths. Notice how your abdominals want to rest on the ball when you inhale.
Exhale and pull your abdominals away from the ball. Try to keep them pulled away even when you inhale. This is your abdominal engagement.

 

Step 2

Once you have established your abdominal engagement, slowly walk your hands forward until your feet come off the floor. Continue walking out until the fronts of your thighs or knees are resting on the top of the ball in a plank position.

It is important to keep your ribcage knitted together and the abdominals strong in order to maintain a rigid torso. Your legs should be very active so that your entire body is straight as a board and aligned parallel to the floor.
Keep your shoulder blades pulling away from your shoulders and toward your hips. Elbows must be straight and hands directly under your shoulders. Keep your legs active.

 

Step 3

Curling Phase: Exhale and slowly bend your knees towards your chest. The ball will roll forward as your knees tuck under your torso and your hips lift toward the ceiling.
NOTE: This brings your body into somewhat of a handstand position. Be aware of your shoulder strength and keep the elbows straight.

Ideally, your knees are under your hips, your hips are toward the ceiling and your shins are on top of the ball. Hold this position for a breath.

 

Step 4

Lowering Phase: Inhale and straighten your legs, rolling the ball back the plank position.


MODIFICATION: If you are uncomfortable or feeling unsafe with your hips raised and shins on the ball, simply tuck your knees into your chest without lifting the hips.

Step 1

Starting Position: Lie prone (on your stomach) over the top of a properly-inflated stability ball (one that compresses approximately 6" under your body weight) with both feet and hands on the floor, hip- and shoulder-width apart.

 

Step 2

Gently exhale, contract your abdominal/core muscles to stiffen your torso and slowly walk yourself forward, lifting your legs off the floor. Continue walking out until the fronts of your thighs or knees are resting on the top of the ball. Maintain a rigid torso aligned parallel with your legs. Retract and depress your scapulae (pull your shoulder back and down) as your reach your end position, with your arms fully extended and hands positioned directly under your shoulders. To help with stability, try to keep your legs straight and squeezed together. It helps to think about squeezing a quarter between your knees.

 

Step 3

Curling Phase: Exhale and slowly pull your knees towards your chest, rolling the ball forward as your knees tuck under your torso and your hips move upwards. Continue moving until your knees are positioned under your hips and your tibia (shinbone) lies over the top of the ball. Hold this position briefly.

 

Step 4

Lowering Phase: Inhale and push your knees away from your torso, returning your body to the starting position.

Avoid arching (sagging) your lower back or hiking your hips upwards in the starting position. Contract your abdominal, back and glute muscles to keep your torso and legs parallel to the floor.

Comments: When performing this exercise, I feel a healing kind of relief in my lower back. I think I will alternate between this one, bird-dog, and crunches with one leg bent and the other leg straight.

Comments: I use this exercise all the time, for my own workouts and clients. I don't agree that it targets the calves though. It can condition the anterior tibialis if someone keeps their toes on top of the ball with dorsi-flexed ankles, but not in the manner of the photo demonstration. It is great for the abs, lower back and the highly ignored hip flexors which everyone seems to be afraid to train. Exercise increases elasticity and resiliency when performed properly. Lets bury the muscle-binding myth.

Comments: I don't understand if so many of our population has/or will experience low back pain at some point in their life why we would want to place our clients at a greater risk by involving the psoas muscles in exercises such as this. There is no mention of the hip flexor group in the description of this movement. Can anyone actually see if a body is in this position which muscles are actually keeping the body from "breaking in two"? It is good for the person to have, and/or be able to perform such a movement, but what good is it? In today's society, if a person does have a job, it probably involves hours sitting which involves shortening of the hip flexors. Why bring them into the club and "trash" that low back even more? At least when demonstrating a movement such as this let us explain the risk.

Comments: THESE EXERCISES ARE HIGHLY MISSED IN EVERYDAY WORKOUTS. MOST IMPORTANTLY, THEY ARE MUCH NEEDED TO AVOID SHIN SPLINTS AND LOWER LEG CRAMPS.
