"Leg day" refers to a workout session primarily focused on training the muscles of the lower body, including the quadriceps, hamstrings, glutes, and calves. This workout is typically dreaded by many due to the intensity and challenge it presents. However, it is crucial for building overall strength, muscle mass, and functional fitness.

Several exercises are effective for building bigger legs. Squats are a cornerstone exercise for leg development, targeting the quadriceps, hamstrings, and glutes. Variations such as front squats, goblet squats, and Bulgarian split squats can also be included to target different muscle groups and add variety. Additionally, exercises like lunges, leg presses, deadlifts, and calf raises can further enhance leg size and strength. It's essential to incorporate a mix of compound and isolation exercises into your leg day routine to ensure balanced development and maximize muscle growth. Consistency, proper form, and progressive overload are key principles for achieving desired results in leg training.
