MYOYAY Non-Slip EVA Adjustable Fitness Squat Ramps - Two 2-Piece Wedges COMFORTABLE AND DURABLE: The squat wedge blocks are made of high quality high-density EVA foam, which does not have the strange smell of rubber. EVA material is lightweight, wear-resistant, has good elasticity and super impact and pressure resistance. LIGHTWEIGHT AND PORTABLE: The total weight of the 2 pieces of squat wedges is 4lbs, and the single piece is 9.21'' long, 5.5'' wide and 3'' high. The small size and light weight makes it possible to carry it with you wherever you go to exercise. NON-SLIP: A squat wedge has 2 sides designed with raised rippled three-dimensional shape, which can increase the friction when contacting with the sole to prevent slipping and make it safer when exercising. 3 ANGLE DESIGNS: Pair divides into 4 squat wedges that provide 8, 15, and 23 by using them individually and stacked in combinations. 15 angled plates are the optimal angle for the wedges, or they can be adjusted to the other angles to suit different usage habits. WHY USE DEEP SQUAT WEDGES: Professional Squat Ramp are used to elevate the feet and squat deeper, which can reduce injuries and make it easier to maintain balance and stability when weight bearing. Releasing pressure on the lower back, knees, hips and ankles reduces the chance of injury and improves exercise efficiency.
