You have listed a Deadlift as a great way to enhance one's glutes, however showed a young lady performing a Romanian Deadlift (the difference is enormous) with a very dangerous mistake. The video, including the advice bullets, claim having your knees locked is the correct way to complete the lift. In (almost) no lift at all should a lifter have any joints locked, especially the knees. This can lead to a very nasty injury if form is not critiqued and will most likely result in the lifter losing consciousness during the exercise. Locking your knees is not the advice I, as a personal trainer, would give any client, especially a novice. I would just cringe if anybody did that move, called it a Deadlift, and hurt themselves from improper advice that they heard from you...
