With the convenient hollow handle, this calf stretcher can be easily carried anywhere—suitable for stretching exercises at the office, home, gym, or outdoors. 2. Adjustable Slant BoardThis versatile balance board for squats has five adjustable angles: 20°, 30°, 35°, 40°, and 45°. The incline can be adjusted to meet different fitness levels and stretching needs, making each workout more diverse and challenging. 3. Multifunctional Calf StretcherOur slant board is for stretching calves, glutes, heels, and ankles. It effectively helps stretch the front and back of the legs, enhances core strength, and improves overall body flexibility, muscle blood circulation, and mobility. 4. NonSlip DesignThe wooden balance board has an enlarged surface with nonslip sandpaper and an antislip pad on the bottom. This increases friction, prevents involuntary movement, and ensures a comfortable experience during stretching exercises.
