The first exercise is excellent for targeting the glutes.

My suggestions:

•use a barbell (not smith machine) as it requires utilization of more muscles

•stand with feet further apart than normal (outside shoulder width) with feet turned out

•get deep into squat with weight on heels •when exploding back up, make sure to fully engage glutes

•change hand positioning (right vs left hand in front) with every set

How do I train?

I train for performance, not for any other reason at this point in my life.  My weight training solely consists of compound movements and/or supersetting lower body exercises with upper body (shown in video).

Train strong, my friends!
