Glute bridges are an exercise that can strengthen your core muscle groups including glutes and low back muscles as well as stabilising your hamstrings.
The exercise can be progressed by doing on single leg as shown to isolate on gluteal group. This reproduces situations such as when you are standing on one leg when walking and running.
You should look to complete 3-5 sets of 8-12 reps daily during a rehabilitation phase post injury or 3 times per week when simplky strengthening.
