The Wide Plank Side Tap is a bodyweight core stability exercise that challenges your waist and trunk muscles by holding a wide-stance plank while alternately tapping one foot out to the side. The wider base of support reduces stability, forcing the obliques and deep core to work harder to prevent rotation and hip drop throughout each tap.
How to do the Wide Plank Side Tap
- 1Start in a high plank position with your hands directly under your shoulders and your feet set wider than hip-width apart.
- 2Brace your core, squeeze your glutes, and create a straight line from head to heels — no sagging hips or raised backside.
- 3Keeping your hips level and your torso from rotating, lift your right foot and tap it out to the right, roughly 12–18 inches wider.
- 4Return your right foot to the starting position with control.
- 5Repeat on the left side — tap left foot out to the left, then return.
- 6Continue alternating sides for the target number of reps or time, maintaining a rigid, non-rotating plank throughout.
- 7To finish, lower your knees to the floor in a controlled manner.
Form tips
- Think of your torso as a plank of wood — resist any twisting or tilting of the hips as you tap out each foot.
- Exhale as you tap the foot out and inhale as you return; controlled breathing helps maintain intra-abdominal pressure.
- Keep your gaze down at the floor a few inches in front of your hands to maintain a neutral neck position.
- If your hips rotate despite bracing, slow the tempo or reduce the tap distance until your core catches up.
Common mistakes
- Letting the hips rotate toward the tapping side, which means the obliques have stopped resisting and the spine is no longer protected.
- Dropping the hips below the straight-line position between taps, turning the exercise into a partial plank rather than an anti-rotation challenge.
- Tapping so quickly that there is no controlled pause or muscle engagement — speed reduces the core stability demand.
- Holding the breath throughout the set, which raises blood pressure unnecessarily and reduces core endurance over longer holds.
Frequently asked questions
What muscles does the Wide Plank Side Tap work?
The exercise primarily challenges the core and waist muscles — the obliques, rectus abdominis, and transverse abdominis — plus the glutes and shoulder stabilizers that keep you in a rigid plank position.
How is the Wide Plank Side Tap different from a regular plank?
The wider foot stance reduces your base of support and adding a lateral tap creates an anti-rotation demand. Your obliques and deep core must work continuously to prevent the hips from twisting with each tap.
Is the Wide Plank Side Tap good for beginners?
It suits beginners who can already hold a standard high plank for 20–30 seconds. If you struggle to keep the hips level, build plank endurance first before adding the side tap.
How many reps or how long should I hold for the Wide Plank Side Tap?
Aim for 3 sets of 10–15 taps per side (20–30 total), or work for 30–45 seconds per set. Rest for 30–60 seconds between sets.
Can I make the Wide Plank Side Tap harder?
Yes. Wear ankle weights, slow each tap to a 3-second out and 3-second return, or elevate your hands on a surface to shift more load onto the core. A narrower hand stance also increases the stability challenge.
