There are exercises you can also perform even as you use the butt Lift machine. Start by lying on your back with your knees bent and arms at your side. If you’re using a dumbbell, hold this across your hip crease. Your feet should be 12–16 inches (30–40 cm) from your butt. Press into your heels, brace your core, and push your pelvis upward by squeezing your glutes. Ensure your chest does not lift during this movement. Hold for 2 seconds and lower your hips back to the ground. This is one rep. Complete 8–12 reps of 2–3 sets.
