Comments and tips
To raise your body, drive through your heel.
Do not push with your arms.
Instead of keeping your free leg straight and level with your body, you can hold it vertically, as illustrated in the image and video.
To make the single leg glute bridge more difficult, hold a weight plate on your lap.
The single leg glute bridge isolates your gluteus maximus. Your hamstrings, which usually help your gluteus maximus to extend your hip, do not assist because they are put in a position of active insufficiency. This is not ideal. Ideally, your gluteus maximus and hamstrings should be trained together. You can train them together using such exercises as the glute-ham raise and the barbell deadlift. However, that is not to say that you should avoid the single leg glute bridge. Use the exercise to activate your glutes if they need specific attention, or use it as an auxiliary exercise to improve your deadlift.
