This will not grow, the same, in a person who trains him in a gym or with weights, is doing it more than 2 times a week. In fact, I recommend spending only one day a week on the buttocks, since also the legs, most of the exercises such as squats, lunges and deadlifts, stimulate the gluteus. .
For that reason, it is also not good to root your legs and the next day to focus on the buttocks, since everyone is mistreated by the training of the previous day. .
So if for example you train legs on a Wednesday, you can train glutes on Friday or Saturday, so you can recover and grow. .
If you train at home, with routines not as intense as those of a gym. It is possible to train it 3 to 4 times a week that it is no longer hypertrophied as much as the gym and recovery is faster and it is always good to maintain the stimulus. .
In the gym applies the quality, at home applies more quantity and frequency. Unless you have good weights at home and you can also train very hard like in the gym
