Hiking is a great way to exercise and get outdoors, but you may be wondering if it will make your bum bigger. The answer is, it depends. If you are carrying extra weight around your hips and thighs, then hiking may help to tone and slim down your lower body. However, if you are already at a healthy weight, then hiking is unlikely to cause any significant changes to your buttocks size. So, if you’re looking to make your bum look bigger, hiking probably isn’t the best activity for you. But if you’re just wanting to enjoy the scenery and get some exercise, then go ahead and hit the trails!
