In the 4 x 4 matrix, what is the correct order of progression from easiest to hardest?

• A. Standing, Stacked, Suspended, Supported
• B. Supported, Suspended, Stacked, Standing
• C. Suspended, Standing, Supported, Stacked
• D. Stacked, Standing, Supported, Suspended

Answer: (B)

Understanding how support levels shape task difficulty helps explain this progression. Easiest tasks provide the most external support, so you can rely on surfaces or assists rather than your own balance. A Supported position uses that external help, making it the easiest. Moving up in difficulty, Suspended reduces that assistance—you’re partially supported by a harness or similar setup, so your core and stabilizing muscles must work harder. Next, Stacked offers even less stabilization, creating a less stable base that requires greater balance and proprioceptive control. The final posture, Standing, uses no external support at all, demanding full-body coordination and strength. That’s why the order from easiest to hardest is Supported, Suspended, Stacked, Standing.
