Four incline angles for stretching calves, hamstrings, and hip flexors, allowing for deeper and more controlled flexibility. Simple maintenance: wipe with a cloth or rinse with water to quickly restore shine. Versatile use: can be used alone or as part of a broader stretching routine; suitable for all skill levels; friendly for outdoor use. Durable and safe: wearresistant, sturdy PP foam construction supports repeated use and helps reduce injury risk during lowerbody stretching. Practical use scenarios: Before workouts: set to a moderate incline, hold for 20–30 seconds, and repeat 2–3 times to warm up. After workouts: increase the incline for a deeper calf/hamstring stretch; hold for 30–60 seconds per side, 2 rounds. Mobility and rehab: start with a shallow incline and progress gradually to improve flexibility and balance with safe, controlled movements.
