Here's a simple test that can give you a general idea if mobility is holding you back. ⬇️ General buckets: 1. Less than 45 degrees: very stiff 2. 45-60 degrees: stiff 3. 60-75 degrees: mobile 4. 75+ degrees: very mobile Buckets 1 & 2 generally benefit from some attention here, and there's no harm in some basic t-spine work if you fall in buckets 3 & 4 either. | Tread Athletics | Facebook
