Hi Gatsby (Gen)
Heres my 2 cents...
I agree with Meg that lunges are awesome for glutes! I do a lot of lunging. walking lunges, step lunges, reverse lunges...barbells, dumbells, smith lunges..
I personally have a 'Leg day' (Heavy compound exersises) and a seperate 'ham and glute' day. Although no exersise completely isolates a muscle, I like to spend some time focusing on them. I want to have a nice backyard.. Ya know!
I do things like stiff leg deadlifts, lots of lunges, leg curls. We are fortunate enough to have a 'butt blaster' in my gym which I like. I keep a training journal and I try to mix it up and do exersises I haven't done in awhile each time I train that bodypart. One of my favorite exersises for glutes is a deep squat on the smith machine with a severe forward stance. I get under the smith bar (across traps), step forward about 1 1/2 feet (pretty far) so I am leaning against the bar. I squat
to the floor then at the top, I pull in and tighten my glutes. I push through the heels. I also (on leg day) do some qaud focus exersises to finish up after I do my barbell squats, leg presses or whatever. For example front squats (barbell sitting in front of neck across shoulders). It behooves you to spend some time with a trainer if only to learn some new exersises and make sure your form is correct, especially when it comes to heavy leg training.
You do want to make sure everything gets trained because the muscles work together and they have to 'help' each other. It also helps with visual symmetry.
Good luck!!
