They'd basically be strength. Pilates does tend to work the core, and, from my experience taking actually ballet classes in my youth, you use your core a lot in ballet as well. If you're doing a lot of plies, you will be working your rear. If you want a rear "lift", try squats. My bum is definitely a higher and rounder after the addition of regular squats, especially heavy squats with a barbell. I'm also loving beFIt in 90s 30 Day Butt Lift program on YouTube. There's a different workout exery day, a mix of strength and cardio, each 10 minutes long, some days you do two.
