For ATG training and knee rehabilitation, a slant board wins. It elevates the entire foot on a stable platform, enabling the full range of ATG movements — split squats, calf raises, Patrick steps, tibialis raises, and Jefferson curls. A squat wedge only elevates the heel and works best for barbell squats. If you follow the Knees Over Toes protocol, the Exura Slant Board ($84.95) — four adjustable angles, two independent laser-cut steel platforms, 900 lb capacity — is the right tool.
| Feature | Exura Slant Board ATG Native | Squat Wedge |
|---|---|---|
| Elevates | Entire foot — full platform stability | Heel only — less stable for single-leg work |
| ATG exercises | Full library — 7+ movements | Limited — 2-3 movements |
| Single-leg stability | Excellent — wide stable base, two independent platforms | Moderate — heel-only contact less secure |
| Angle progression | 4 angles — 20°, 25°, 30°, 40° (tool-free) | Usually fixed or 2-3 angle options |
| Platform design | Two independent laser-cut steel platforms — asymmetric foot placement | Single piece — locked stance |
| Build | Rigid laser-cut steel — zero flex under load | Varies — foam, wood, or plastic depending on model |
| Capacity | 900 lb static capacity | Varies by model |
| Knee rehab | Full protocol — Patrick steps, calf raises, split squats, tibialis raises | Limited — primarily heel-elevated squats only |
| Barbell squats | Works well | Excellent — low profile, high stability under bar |
| Portability | Moderate | High — compact, lightweight |
| Best for | ATG protocol, knee rehab, full lower leg training | Heavy barbell squats, casual heel elevation |

The ATG protocol is built around single-leg movements — the split squat and the Patrick step. Both require a stable base under the entire front foot. A wedge under only the heel creates instability in unilateral movements. The Exura Slant Board's two independent steel platforms give you the stability — and the asymmetric foot placement — to focus on depth and range, not balance.
The Patrick step — one of the most powerful knee-strengthening exercises in the ATG protocol — requires stepping down off an elevated surface. A squat wedge cannot do this. The Exura Slant Board doubles as the platform for step-up progressions, making it a far more complete knee rehabilitation tool.
The slant board calf raise and tibialis raise are core ATG movements for building ankle and knee resilience. Both require standing on the inclined platform — heel and forefoot both in contact. A wedge under the heel cannot replicate this. These exercises simply do not work on a squat wedge.
A squat wedge is a legitimate tool — just for a different purpose. If your primary training is heavy barbell squatting and you want heel elevation without a bulky board, a wedge can do the job. For ATG protocol, knee rehabilitation, or lower leg conditioning, the slant board covers everything a wedge does and much more.
