If you want to boost your bench, squat, and deadlift, build your butt and improve your running and jumping form, then you must add the weighted single-leg hip thrust to your routine.
First, you should be able to do 10 body-weight reps on each side before progressing to the loaded version.
Once you can do that with perfect form, place a dumbbell in your supporting leg's hip crease. Do 3 to 4 sets of 5 reps on each side. Keep your abs crunched throughout the exercise, and move at your hips, not at your lower back.

Finish with a burnout set of as many body-weight reps as possible on each leg to pump up your glutes like Ball Park franks.
