My Fiance: 26yrs Old, 121 lbs Lifting for 4yrs

She’s gone back and forth over time between compound, big movements only like squats, deadlifts, clean and jerk and more iso stuff like kickbacks and butt blaster. What do you think would help take her to the next level?

What ‘next level’ are you referring to? Competing?

squat + walking lunge superset for a next level bootie
