The squat is the king of all exercises. You can perform it with your body weight, with dumbbells, or with a barbell. We recommend using a barbell if you can to increase the stimulus of the exercise.
The deadlift allows the most amount of weight to be lifted in one exercise. To do it properly, it requires a great deal of hip extension which activates the glute max. You can perform the conventional deadlift or the sumo deadlift.
