Should I get a 17 or 25 slant board?

The beauty of the GymFit Tech system is that it renders this specific dilemma obsolete by offering a modular solution. A standard 15-17 degree board is great for general squats, while 25+ degrees is used for extreme quad isolation and rehab.

The GymFit Tech Elevate Heel Blocks provide a 10-degree incline individually, which is perfect for general high-bar squats, and can be stacked to create a 20-degree incline.

 This 20-degree angle sits in the "sweet spot" between the two common fixed sizes, offering enough steepness for aggressive VMO targeting and "knees over toes" work without being too extreme for regular compound lifting. Instead of buying two separate fixed boards, the GymFit Tech stackable design covers the entire spectrum of training needs effectively.
