The Push-up Jack combines a standard push-up with a jumping jack leg movement, making it a dynamic bodyweight exercise that challenges the chest, shoulders, and triceps while demanding continuous core engagement. As you lower and press through each rep, your legs jump out wide and back together, adding a cardiovascular demand on top of the upper-body work. It is well suited for circuit training, conditioning work, or any session where you want to build pressing strength and elevate your heart rate simultaneously.
How to do the Push-up Jack
- 1Start in a high plank position with your hands slightly wider than shoulder-width apart, arms fully extended, and your body forming a straight line from head to heels.
- 2Engage your core and squeeze your glutes to keep your hips level — they should not sag toward the floor or pike upward.
- 3Begin lowering your chest toward the floor by bending your elbows at roughly a 45-degree angle from your torso.
- 4As you lower down, jump both feet out wide simultaneously — landing softly with your feet wider than hip-width, as you would at the bottom of a jumping jack.
- 5Descend until your chest nearly touches the floor, keeping your elbows from flaring out to 90 degrees.
- 6Press through your palms to extend your arms back to the starting position.
- 7As you push up, jump both feet back together so they return to their starting position at the top of the rep.
- 8Exhale as you press up and inhale as you lower down, maintaining a controlled tempo throughout.
- 9Continue for the desired number of repetitions, landing softly on the balls of your feet each time to protect your joints.
Form tips
- Keep the foot jump and the push-up in sync — your feet should land wide at the bottom of the push-up and return together as you lock out at the top.
- Land softly on the balls of your feet rather than your heels each time you jump to reduce impact on your ankles and knees.
- Maintain a rigid plank through your midsection for the entire set — every time your hips drop or sag, tension transfers away from the chest and onto the lower back.
- If the movement feels unstable, slow the tempo and focus on controlled landings before increasing speed.
- Keep your gaze slightly ahead of your hands rather than straight down — this helps maintain a neutral cervical spine throughout the movement.
Common mistakes
- Letting the hips sag as the feet jump out: the added leg movement often causes the lower back to collapse, removing tension from the chest and increasing spinal stress.
- Jumping the feet before initiating the push-up descent: the legs and upper body should move together — separating them turns a coordinated drill into a sloppy combined movement.
- Landing heavily on the heels: a hard heel strike sends impact force up through the knees and hips and also destabilizes the plank position, making the following push-up harder to control.
- Flaring the elbows out to 90 degrees: this places unnecessary shear stress on the shoulder joint and reduces chest activation through the range of motion.
- Rushing the reps to keep up cardio intensity: moving too fast at the expense of range of motion means the chest never reaches full stretch at the bottom, significantly reducing the training stimulus.
Frequently asked questions
What muscles does a Push-up Jack work?
The Push-up Jack primarily targets the chest and relies on the shoulders and triceps as main contributors during the pressing motion. Your core works continuously to keep the plank stable as your legs jump in and out, and your hip abductors are active each time your feet move wide.
Is the Push-up Jack a cardio or strength exercise?
It is both. The push-up component builds upper-body pressing strength, while the jumping jack leg movement raises your heart rate and adds a conditioning demand. It fits naturally into circuit training, HIIT, or bodyweight strength sessions.
Can beginners do Push-up Jacks?
Beginners should first be comfortable performing standard push-ups and jumping jacks separately before combining them. If coordination is a limiting factor, practice the timing by stepping one foot out at a time instead of jumping both feet simultaneously.
How do I make Push-up Jacks easier or harder?
To make them easier, perform the push-up on your knees and step your feet out instead of jumping. To increase difficulty, increase the pace, add a pause at the bottom of each rep, or incorporate them into a timed circuit with minimal rest.
Where should my feet land when I jump them out?
Your feet should land wider than hip-width — approximately the same position as the bottom of a standard jumping jack. Land on the balls of your feet with a slight bend in the knees to absorb the impact and stay in a stable plank position.
