The resistance band plank jack is a core exercise that combines a standard plank hold with a jumping-jack leg motion to challenge the waist and abdominals under constant tension. The band looped around the ankles adds resistance to the outward leg drive, increasing demand on the hip abductors and deepening core engagement throughout each rep.

How to do the Resistance Band Plank Jack

  1. 1Place a resistance band around both ankles and position yourself in a high plank with hands directly under shoulders, body forming a straight line from head to heels.
  2. 2Brace your core, squeeze your glutes, and set your hips level — avoid letting them rise or sag.
  3. 3Keep your arms locked and your gaze just ahead of your hands so your neck stays neutral.
  4. 4Jump both feet out to the sides simultaneously against the band's resistance, landing with feet wider than hip-width.
  5. 5Immediately jump both feet back together to the starting position, maintaining a rigid torso throughout.
  6. 6Continue alternating out-and-in jumps at a controlled, steady tempo for the desired number of reps or time.
  7. 7To finish, step one foot at a time back to the center position, then lower to the floor in a controlled manner.

Form tips

  • Keep your hips level the entire set — do not let them pike up or drop down as your legs move.
  • Breathe steadily; exhale as you jump the feet out and inhale as you bring them back in.
  • Choose a band resistance that lets you maintain full plank form; if your hips shift noticeably with each rep, use a lighter band.
  • Press the floor away with your hands and pull your navel toward your spine to keep the core actively engaged, not just passively held.
  • Land softly on the balls of your feet to reduce impact and keep the movement controlled rather than bouncy.

Common mistakes

  • Letting the hips pike upward: raising the hips shifts load away from the core and makes the movement far easier than intended.
  • Allowing the lower back to sag: a sagging lumbar spine places excess stress on the spinal erectors and reduces core tension.
  • Rushing the tempo: moving too fast causes the torso to rotate and the hips to drift, turning the exercise into an uncontrolled flail rather than a core drill.
  • Positioning the band too high on the legs: placing the band above the ankles reduces the lever arm and diminishes the abduction challenge — keep it at the ankles.
  • Looking straight down at the floor: dropping the head rounds the upper spine; keep your gaze a few inches in front of your hands to maintain a neutral neck.

Frequently asked questions

What muscles does the resistance band plank jack work?

The exercise primarily targets the core and abdominals, which work to keep the body rigid in the plank position. The resistance band adds challenge to the hip abductors as the legs drive outward against the band on each rep.

Can I do resistance band plank jacks without jumping?

Yes. Step each foot out and back in one at a time instead of jumping. This low-impact variation reduces spinal load and is useful if you are new to the exercise or working on a hard surface.

How many reps or how long should I hold resistance band plank jacks?

Aim for 20–30 seconds or 15–20 reps per set as a starting point. Prioritize maintaining strict plank form over hitting a specific number — stop the set when form breaks down.

What resistance band should I use for plank jacks?

Start with a light to medium loop band placed around the ankles. The band should provide noticeable resistance when you abduct your legs but not so much that it causes your hips to shift or rotate.

Where do resistance band plank jacks fit in a workout?

They work well as a core finisher at the end of a strength session or as part of a circuit. Because they also elevate the heart rate, they can double as a conditioning drill between heavier sets.
