Exercising is the most effective way to grow your bum faster. When it comes to working out, focus on exercises that target the glutes, such as squats and lunges. Squats are great for targeting all three muscles of the gluteal complex (gluteus maximus, medius and minimus), while lunges emphasize more on the gluteus maximus. For best results, aim to do two or three sets of 10-15 reps per exercise twice a week. Additionally, you can use resistance bands around your ankles during squats or lunges to increase difficulty levels and also add bridges into your routine for an extra challenge. Eating healthy is also key in adding size to your buttocks; make sure you're consuming enough protein from quality sources like eggs, lean meats and legumes as this will help you build more muscle mass which is essential for bigger bums! Finally, rest days are just as important as workout days—give yourself time off between workouts so that your body can recover and rebuild itself stronger than before
