Iron Cross Plank
The Iron Cross Plank challenges your core stability and strength. You engage multiple muscle groups while maintaining a plank position.
- Start in a plank position with your hands directly under your shoulders.
- Lift your right arm and left leg simultaneously, extending them out to the sides.
- Hold for a moment, then return to the starting position.
- Alternate sides, lifting your left arm and right leg.
- Continue alternating for the desired duration.
How to perform the Iron Cross Plank
- Set up. Set up in a stable, balanced starting position appropriate for the Iron Cross Plank using your body weight.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your abdominals rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
