How To Do
Start in a high plank with your hands under your shoulders and your body in a straight line. Jump your feet out wide, then back together, keeping your core engaged and hips level throughout. Maintain a steady pace and avoid letting your hips sag or rise.
Step-by-Step Instructions
- Begin in a high plank position with your hands directly under your shoulders and your body forming a straight line from head to heels. Engage your core and keep your back flat.
- Jump both feet outwards to the sides, wider than shoulder-width apart, while maintaining the plank position. Avoid letting your hips sag or rise too high.
- Jump your feet back together to the starting position, keeping your core tight and your body stable.
- Repeat the movement for the desired number of repetitions or time duration, ensuring controlled and steady jumps throughout.

Frequently Asked Questions
- What muscles does the Jack Plank work?
- The Jack Plank primarily targets your abs and obliques, helping to strengthen your core. It also engages secondary muscles including the shoulders, glutes, and upper legs, making it a full-body movement that improves stability and endurance.
- Do I need any equipment to perform Jack Planks?
- Jack Planks are a bodyweight exercise and require no equipment, making them suitable for home workouts or gym sessions. You simply need enough floor space to hold a plank position and safely jump your feet in and out.
- Is the Jack Plank suitable for beginners?
- Yes, beginners can perform Jack Planks, but it’s important to start slowly to build core strength and stability. If jumping the feet feels too challenging, you can modify by stepping them out one at a time while holding the plank.
- What are common mistakes to avoid when doing Jack Planks?
- Avoid letting your hips sag or lift too high, as this reduces core engagement and can strain your lower back. Also, keep your shoulders stacked directly over your wrists and maintain a controlled pace to prevent poor form.
- How many sets and reps should I do for Jack Planks?
- For general fitness, aim for 3 sets of 20–30 seconds at a steady pace, or count 12–20 repetitions per set. Adjust volume based on your fitness level and use proper form throughout each set.
- Are Jack Planks safe for people with lower back issues?
- Jack Planks can be safe if performed with proper form and a strong core, but those with lower back problems should proceed cautiously. Modifying to a slower step-out plank or reducing duration can help limit strain while still providing benefits.
- What variations can I try to make Jack Planks more challenging?
- You can increase intensity by adding a push-up between jumps or performing them on forearms for greater core demand. Using a resistance band around the ankles can also boost glute activation while keeping the movement dynamic.
