1. What is the difference between the two wedges?
Travel Wedgiez were built for busy professionals who need a compact wedge they can bring to their workouts. They have an extra grip on the bottom surface sp that you can train anywhere. Also, they are built out of a high-density polyethylene material capable of holding up to 750 pounds.
The XL Wedgiez are much larger and give you a greater range of heel elevation. They are ideal for larger feet or those who need a higher heel elevation to squat. They are built out of high-density foam that can hold up to 500 pounds. Deformation of the foam is common after a heavy lift, but it will bounce back to its standard shape.
2. What does elevating the heel do?
Elevating the heel shifts your center of mass backward so that you have more space for your knees to go forward. This will allow for a deeper squat movement that will target the thighs and glutes more compared to a partial range of motion squat.
Elevating the forefoot shifts your center of mass forward giving you more space for your hips and knees to pull backward. Having the toes elevated can prevent excessive forward knee movement in a Romanian deadlift or hip thrust. Also, elevating the forefoot will extend the toes, which will improve ankle mobility.
Also, you have to stack three five-pound plates to get the same heel elevation as Squat Wedgiez. Weight plates leave gaps between your feet and the ground, decreasing your balance and reducing the sensory information needed for your ankle and foot to work optimally.
