The elbow to knee side plank crunch is a bodyweight core exercise that targets the obliques and rectus abdominis while strongly engaging the gluteus maximus and medius and the quadriceps. Driving the top elbow toward the top knee under tension, it also recruits the adductors, gracilis, pectineus, and tensor fasciae latae to build rotational core strength and lateral hip stability.
Cómo hacer el Elbow to Knee Side Plank Crunch
- 1Lie on your side with your legs stacked and your forearm flat on the floor, elbow directly under your shoulder.
- 2Brace your core and lift your hips off the floor into a side plank, forming a straight line from head to feet.
- 3Extend your top arm overhead and reach your top leg slightly forward to set your starting position.
- 4Exhale and crunch by driving your top elbow and top knee toward each other over your torso.
- 5Squeeze your obliques and glutes hard at the point where elbow meets knee.
- 6Inhale and slowly return your arm and leg to the extended starting position without dropping your hips.
- 7Complete all reps on one side, then lower under control, switch sides, and repeat.
- 8Keep your supporting hip lifted and your spine long throughout every rep.
Consejos de técnica
- Keep your hips stacked and lifted so the work stays in your obliques and glutes rather than collapsing toward the floor.
- Move at a controlled tempo and pause briefly at full crunch instead of swinging the limbs for momentum.
- Press your supporting forearm firmly into the floor to stabilize your shoulder and protect the joint.
- Exhale on the crunch and inhale on the return to maintain bracing and rib-to-pelvis connection.
- If holding the side plank is too hard, drop your bottom knee to the floor for support while you crunch.
Errores comunes
- Letting the hips sag toward the floor, which removes tension from the obliques and strains the lower back.
- Yanking the elbow and knee together with momentum, which cheats the rep and reduces oblique recruitment.
- Rolling the chest or hips forward, which turns the move into a flat crunch and loses the lateral stability work.
- Stacking the supporting elbow ahead of or behind the shoulder, which places uneven stress on the shoulder joint.
- Holding the breath through the crunch, which weakens core bracing and limits how hard you can contract.
Preguntas frecuentes
What muscles does the elbow to knee side plank crunch work?
It primarily works the obliques and rectus abdominis along with the gluteus maximus, gluteus medius, and quadriceps. The adductors, gracilis, pectineus, and tensor fasciae latae assist to stabilize the hip.
How many sets and reps should I do?
Aim for 2–3 sets of 8–15 reps per side. Stop when your hips start to drop or your form breaks down, since clean reps train the obliques better than high numbers.
Is the elbow to knee side plank crunch good for beginners?
Yes, with a regression. Beginners can drop the bottom knee to the floor for a supported side plank, then progress to a full side plank once they can hold a straight line.
Where should I feel this exercise?
You should feel it mainly in the side of your waist (the obliques) on the working side, with the glutes and quads working to keep your hips lifted and stable.
What is a good alternative to this exercise?
A standard side plank builds the same lateral stability without the crunch, while bicycle crunches train the obliques with rotation. Both are bodyweight options that pair well with this move.
