The best wedge angle for squats will vary depending on the individual's needs and goals. Generally, a slightly higher wedge angle of 45-60 degrees is considered ideal for most people as it allows for greater stability in the lower back while performing the squat exercise. By creating a slight forward lean with your upper body, this helps to keep your spine in better alignment throughout the movement which can help reduce any potential risk of injury associated with excessive torso rotation or overextension of muscles during certain parts of the exercise. Additionally, a higher wedge angle also helps to target specific muscle groups more effectively such as quadriceps and glutes by allowing you to lower down further into the squat position without compromising form or technique. Ultimately, however, it’s important to experiment with different angles until you find one that works best for you and meets all your fitness goals.
