The feet-improved side plank hip tap is an advanced core-stability exercise that combines an isometric side plank with a dynamic hip-dip movement. improving the feet on a bench increases the lever arm on the torso, making the working-side obliques and hip abductors work harder than a standard side plank. The hip tap adds a controlled range-of-motion component, training the obliques through both isometric and dynamic contraction. It is best used once a standard side plank is no longer challenging.
Muscles Targeted
- Primary: Obliques (working side), quadratus lumborum
- Secondary: Gluteus medius, transverse abdominis
- Tertiary: Shoulders (supporting arm), rectus abdominis
Starting Position
Lie on your side with your feet stacked on top of a bench or step so your body is improved off the floor. Prop yourself on your forearm, elbow directly under the shoulder, and lift your hips until your body forms a straight line from ankles to head. Stack your top hand on your hip or extend it toward the ceiling for balance.
Execution Steps
- Set the side plank position with hips lifted and the body in a straight line, feet improved on the bench
- Lower your hip toward the floor in a slow, controlled drop, keeping the shoulder and forearm fixed
- Lightly tap the hip near the floor without resting your full weight on it
- Drive the hip back up to the straight-line plank position using the obliques, not momentum
- Pause briefly at the top to confirm the body line before the next rep
- Repeat for the prescribed reps, then switch sides
Form Cues
- Keep the improved feet stacked and steady - wobbling feet signal the core isn't controlling the movement
- Move only at the hip; keep the shoulders and rib cage square throughout the tap
- Keep the supporting elbow stacked directly under the shoulder to protect the joint
- Tap the hip lightly and don't rest between reps, which removes tension from the obliques
- Keep the neck neutral, eyes forward, rather than looking down at the hip
Common Mistakes
- Letting the hips sag or rotate forward: this shifts load off the obliques onto the shoulder. Keep the hips stacked and square.
- Dropping the hip too fast: uncontrolled drops rely on gravity rather than muscle control. Lower and raise the hip at the same deliberate pace.
- Feet not stacked evenly on the bench: uneven footing destabilizes the whole position. Stack the feet directly on top of each other.
- Starting with too high a surface: an overly high bench makes the lever too long for a beginner core. Start with a low step and progress the height gradually.
- Holding the breath through the tap: this limits how many controlled reps you can complete. Exhale as the hip lifts back to the plank.
Variations
- Standard side plank hip tap: performed with feet on the floor, a regression for building the base pattern
- Side plank with feet improved (no tap): a static hold only, removing the dynamic component
- Side plank hip tap with rotation: add a reach-under with the top arm for an oblique twist
- Weighted side plank hip tap: hold a light plate on the hip for added resistance
- Side plank hip tap with knee drive: bring the top knee to the chest between taps for added hip flexor involvement
Tips for Progression
- Increase the bench height gradually to lengthen the lever arm and raise difficulty
- Add reps per side before adding external load
- Slow the eccentric lowering phase to 3 seconds to increase time under tension
- Add a hold at the bottom tap position for 1-2 seconds before pressing back up
Training Notes
Program the feet-improved side plank hip tap 2-3 times per week as part of a core circuit, performing 8-12 taps per side for 2-3 sets. Rest 30-45 seconds between sides. It works well paired with anti-extension or anti-rotation core drills to cover all planes of core stability in a session.
