what it claims
If your heels lift off the ground when you squat, it indicates restricted ankle dorsiflexion mobility. Performing a targeted joint mobilization exercise can help restore this range of motion, allowing for a full, fluid, and balanced squat.
The relationship between a lack of ankle dorsiflexion and limited squat depth is widely validated by observational studies (such as those by Kim et al., 2015).
