Dynamic stability

What is dynamic stability?

This parameter measures the side-to-side wobble of your hips and provides insight into your ability to stabilize your hips while running. A lower score, shown as orange or red, indicates poor hip control which increases the work of your stabilizing muscles. This reduces your running efficiency (or how much energy you consume) and increases the risk of overuse injuries (e.g. MTSS, ITB syndrome)

How to improve your dynamic stability?

Dynamic stability training is a great way to strengthen the muscles that help stabilize your pelvis while running, such as your abs, back, and glutes. With a progressive series of exercises, you can develop your muscles from isolated work to more dynamic movements, helping you feel more stable while you run.

You can follow a training framework that incorporates different types of exercises. Isolated and static exercises primarily target the strength(-endurance) of the stabilizing muscles. In contrast, dynamic and reactive exercises aim to enhance how the muscles work together
By incorporating both isolated/static and dynamic/reactive exercises into your training plan, you can develop a stronger, more balanced body and become a more efficient runner. So, mix up your workouts and enjoy the benefits of a varied training program!

Example exercises

* Please note that the exercises provided are for illustrative purposes only and may not be suitable for everyone. We recommend discussing these exercises with your Runeasi-expert to determine if they are appropriate for your individual needs and abilities.

Hip flexor mobility / flexibility

E.g. 4 x 15 sec hold 

Isolated/Static: Sideplank knee lift

E.g. 3 x 8 Alternating left & right – rest 30″ 

Isolated/Static: Swissball – wall marches

E.g. 3 x 15 R30″

Dynamic: Backward lunge + sidesling

E.g. 3 x 8 R30″ between left & right

Reactive: skip & hold – loose weights

E.g. 4 x 16 R1′

5. Quick comparisons

Compare pre-post data to show intervention effects on the movement quality. 


1. No motion artifacts. The Runeasi belt is secured tightly against the body and the skin to capture the actual movements of the body’s center of mass. Attaching or clipping the sensor directly to the pants would allow the sensor to wobble from side to side (i.e., measuring the wobbling of the pants, and not the human body.

2.  Easy to standardize the sensor’s positioning. The Runeasi belt makes it easy to consistently position the sensor close to the center of mass. Attaching the sensor directly to the pants would dramatically affect the reliability of the outputs as the height and tightness of the pants will affect the results. Moreover, these pants attachments often shift sideways while running which further decreases the data quality. 

 3. Comfortable to wear.  Hundreds of runners confirmed that they immediately forget about our belt while running. This allows them to move without any restrictions and allows us to capture movements that are representative of a client’s true biomechanics.
