To grow your legs and glutes you have to be very patient because there will be setbacks and there will be moments where you feel weak. The number one thing you have to do is eat protein and I mean a lot of it depending on your goal. Glutes are the most stubborn muscle to grow, you have to train hard and lift heavy. On top of that you have to allow time for your muscles to rest before you can work out again. If you are training your glutes daily then you are doing more harm than good, don't be surprise if your glutes are getting smaller. You have to train maximum 3 times a week, no more than that. You have to allow 24-48 hours in between each session to let your lower body rest before you train again. In between each rest just consume a lot of protein and sleep at least 7 hours a night.
Honestly I love the process and you can only fall in love with it if you're not in a rush, because if you want big glutes by next week sorry to break it to you that will simply not happen. You have to be patient and keep working hard. When you acheive your goal, you might not even realize it until someone else comment on it but of course you'll see the progress in the mirror. Some days you won't see the progress because you've seen yourself daily but what I suggest in that case is look at past pictures from 6 months ago you'll see the diffrence trust me.
