If you’re looking to maximize your squat performance, understanding the significance of ankle and hip range of motion is crucial.
We read a number of papers dating back to 2015 and they all had two common findings that related to squatting ability:
- An ankle dorsiflexion range of motion of >12cm on the knee-to-wall test
- Hip Flexion range of motion of >125˚
Numerous studies have highlighted these two aspects as the best predictors of achieving a deep squat. Notably, research from 2015 (Kim et al), 2020 (Endo at al) and 2022 (Gomes et al) emphasized that sufficient mobility in these joints is essential for effective squatting.
Let’s dive deeper into each component, how to test your mobility, and strategies to improve it!
Ankle Range of Motion
How Much Flexibility Do I Need and How Do I Test It?
When it comes to ankle mobility, specifically dorsiflexion, research indicates that you need a minimum of 12 cm on the knee-to-wall test to perform a full squat effectively. A 2015 paper in the Journal of Human Kinetics assessed 101 individuals To assess your ankle range of motion, the knee-to-wall test is a popular and straightforward method. Here’s how it works:
- Stand facing a wall and place your foot about 12 cm away from it.
- Keeping your heel on the ground, bend your knee and try to touch it to the wall.
- Measure the distance from your toes to the wall—this will help you determine your dorsiflexion.
