It's super important that you THINK about your glutes during every second of those 15min and try to make them BURN. Means you try to
1) squeeze your butt for every repetition
2) move your leg with the "strength" of your glutes and not by swinging
3) don't release tension and relax at the lower point of the motion (e.g. the lower point of a glute bridge), but rather KEEP the tension during the entire movement and squeeze "even more" at the upper point of the motion.
If you need breaks - TAKE THEM! Don't worry too much about that. You will improve over time 🙂 that's the best feeling! The video is in full length which means you can just follow whatever Pamela Reif is doing 30s for each exercise.
