Five adjustable angles (20°, 30°, 35°, 40°, 45°) provide a gradual progression in flexibility training. The nonslip foam mat offers stable support during deep stretches, while the ergonomic design reduces pressure on the knees and Achilles tendons for postrun recovery or preworkout warmups. Antislip weighted rubber base with textured foam surface keeps the board securely in place on hardwood, tile, or carpet. The 2 cm thick cushioning protects joints during stretching, making it suitable for yoga and physical therapy exercises. Foldable and portable: collapses to a compact 4 inch thickness and weighs 4.41 lbs for easy storage under beds or in closets. Convenient for travel, office breaks, or gym workouts. Can be used at a standing desk to mitigate plantar fasciitis or during leisure time for gentle stretching. Versatile for flexibility and toning: ideal for athletes seeking to enhance calf flexibility for running and jumping. Suitable for yoga and Pilates practitioners to deepen poses such as Downward Dog or Warrior, and helps relieve tightness from heels or prolonged sitting.
