The suspension crunch is a core strength exercise performed with a suspension trainer, where you hold a plank position with your feet in the straps and draw your knees toward your chest. It targets the iliopsoas and rectus abdominis as the primary movers, with the obliques assisting throughout the movement. The unstable surface created by the straps increases the demand on stabilizing muscles compared to floor-based crunch variations.
Suspension Crunch: So führst du sie aus
- 1Set the suspension trainer so the foot cradles hang about 12–18 inches off the floor.
- 2Kneel in front of the anchor point, place one foot at a time into the cradles, and extend into a high plank position with your hands directly under your shoulders.
- 3Brace your core, squeeze your glutes, and establish a straight line from your heels to the top of your head before starting any movement.
- 4Exhale and draw your knees toward your chest by rounding your lower back and contracting your abs, allowing your hips to rise as your knees come in.
- 5Pause briefly at the top when your knees are near your elbows and your abs are fully contracted.
- 6Inhale and slowly extend your legs back to the starting plank position, resisting the pull of gravity throughout the return.
- 7Repeat for the desired number of reps, keeping your hips level and your core engaged on every rep.
Technik-Tipps
- Initiate the movement from your abs, not by swinging your hips — think of compressing your torso rather than just pulling your legs in.
- Keep your arms straight and your shoulders stacked over your wrists throughout the set to maintain a stable base.
- Control the extension phase as carefully as the crunch — rushing back to the plank lets your lower back sag and reduces ab tension.
- Adjust strap height if your hips drop or you cannot hold a neutral spine in the starting plank; lowering the cradles keeps your feet closer to floor level and makes the plank easier to hold.
Häufige Fehler
- Letting the hips sag in the plank position, which shifts load away from the abs and stresses the lower back.
- Using momentum to swing the knees in rather than contracting the abs, which reduces core activation and can strain the hip flexors.
- Tucking the knees only partway so the hips never rise, which keeps the abs from fully shortening and leaves the rep to the hip flexors.
- Holding your breath through the set, which makes it harder to fully contract the abs and spikes blood pressure — exhale as you crunch in.
Häufig gestellte Fragen
What muscles does the suspension crunch work?
The primary movers are the iliopsoas (hip flexors) and rectus abdominis (the 'six-pack' muscle), with the obliques assisting by resisting rotation and keeping your hips square throughout the movement.
How is the suspension crunch different from a regular crunch?
Because your feet hang in unstable straps, your core must work harder to maintain balance and control, engaging more stabilizing muscle activity than a crunch performed on the floor.
Is the suspension crunch suitable for beginners?
It is an intermediate-level exercise. You should be comfortable holding a solid plank for at least 30 seconds and have basic core strength before attempting it.
How many reps should I do?
For core strength, 3–4 sets of 8–15 controlled reps is a common range. Prioritize quality of movement over rep count — stop if your form breaks down.
Can I make the suspension crunch harder?
Yes — you can increase difficulty by extending your legs fully on each rep (a pike variation), slowing the tempo, or pausing for 2–3 seconds at the top of each crunch.
