Hip-Thrust Crunch with Oblique Twist

The hip-thrust crunch with oblique twist is a floor-based bodyweight exercise that chains three movement patterns into a single rep: a glute bridge, a spinal flexion crunch, and a rotational reach toward the opposite knee. It trains the rectus abdominis and obliques through both flexion and rotation while also activating the glutes and hamstrings during the hip-thrust portion. Because the hips stay lifted between reps, the abs and glutes stay under near-continuous tension rather than resetting on the floor.

Muscles Targeted

• Primary: Rectus abdominis, obliques
• Secondary: Gluteus maximus, hamstrings
• Tertiary: Hip flexors, transverse abdominis

Starting Position

Lie on your back on a mat with your knees bent, feet flat on the floor about hip-width apart, and heels close enough to your glutes to allow a strong hip drive. Place your fingertips lightly behind your head with elbows flared out to the sides - don't lace your fingers or pull on your neck. Press your lower back gently into the floor to engage your core before you begin.

Execution Steps

1. Drive through your heels and lift your hips off the floor, squeezing your glutes hard at the top of the bridge
2. Hold the bridge for a one-count, keeping your hips level and your core braced
3. Lower your hips only partway, stopping just above the floor to keep tension on the glutes and abs
4. Curl your shoulder blades off the mat into a crunch, leading with your chest rather than yanking your head forward
5. Rotate your torso and reach one elbow toward the opposite knee, squeezing the obliques on that side
6. Return to the hovering hip-thrust position and repeat the crunch-and-twist toward the other side
7. Continue alternating sides, keeping the hips lifted between every rep

Form Cues

• Squeeze glutes, not lower back: The hip lift should come from glute contraction, not from arching and straining the lumbar spine
• Lead the crunch with your chest: Curl your ribs toward your pelvis instead of pulling your chin toward your chest
• Rotate from the ribcage: Twist through the torso, not just the arm reaching across
• Keep hips level during the twist: Don't let one hip drop or rock as you rotate to each side
• Exhale on the crunch-and-twist, inhale as you reset to the hovering bridge

Common Mistakes

• Resting the hips fully on the floor between reps: This removes tension from the glutes and abs and turns the exercise into two separate movements. Keep a slight hover throughout the set.
• Pulling on the neck during the crunch: Yanking the head forward with the hands can strain the cervical spine. Keep elbows wide and let the abs do the lifting.
• Overarching the lower back at the top of the thrust: Hyperextending the spine shifts load off the glutes. Stop the lift once the hips and torso form a straight line.
• Rotating only the arm instead of the torso: This reduces oblique engagement. Turn the shoulders and ribcage toward the opposite knee.
• Rushing the tempo: Moving too fast relies on momentum instead of muscle control. Slow down and pause briefly at both the bridge and the twist.

Variations

• Bicycle crunch: Removes the hip-thrust component for a purely rotational ab exercise with continuous leg movement
• Glute bridge march: Isolates the hip-thrust portion with alternating leg lifts to add a stability challenge
• Weighted crunch with twist: Holding a light plate or dumbbell against the chest increases resistance for the rotational crunch
• Stability ball hip thrust crunch: Performing the bridge with feet on a stability ball adds a balance component to the glute work
• Standing cable woodchop: A standing alternative that trains rotational core strength under external resistance

Tips for Progression

• Slow the tempo: Add a 2-3 second pause at both the top of the hip thrust and the peak of the twist to increase time under tension
• Increase reps per side: Progress from 10-12 to 15-20 reps per side before adding external load
• Add resistance: Hold a light dumbbell or plate against the chest once bodyweight reps feel controlled and easy
• Slow the eccentric: Control the return from the twist back to center rather than letting momentum carry you

Training Notes

Use this exercise 2-3 times per week as part of a core-focused segment, typically placed after your main strength work. Perform 2-3 sets of 10-15 reps per side, resting 30-45 seconds between sets. Because it combines hip extension with rotational and flexion work, it pairs well in a circuit with planks or dead bugs to round out anti-extension and anti-rotation core training.
