How many times you perform hip thrusts will depend on your needs and goals. Performing more reps in a small window of time does not mean that you will see faster or better results.  If your goal is to develop your glute muscles or improve glute strength, there are a few things worth considering such as: focus on providing the right stimulus, ensuring good form, applying progressive overland and getting adequate rest, to achieve optimal results. If you’re not sure how many times would be optimal to perform this exercise, you can ask help from a personal trainer in the gym.
