Outdoor fitness equipment dimensions can vary widely depending on the type of equipment and its intended use. For example, treadmills typically range in length from 48 to 60 inches, while elliptical trainers can range from 50 to 80 inches in length. Strength training equipment like weight benches and leg press machines can vary in size based on their capacity and design. It's important to ensure that the equipment fits comfortably within the designated space and meets safety standards.
