Leg Front Kick

  • Beginner
  • Compound
  • Rep-based
  • Hips
  • Lower legs

The Leg Front Kick is a dynamic compound movement that develops explosive quadriceps power and hip flexor strength while challenging core stability and shoulder endurance. It improves functional balance and coordination by requiring a stable base while the opposite limb performs a controlled strike.

Muscles worked

Primary

  • Deltoids

Secondary

  • Hip flexors

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart and a slight bend in your knees.
  2. Bring your hands up to chin level in a 'guard' position, keeping your elbows tucked and deltoids engaged.
  3. Shift your weight slightly onto your left leg while keeping your core tight and chest upright.

How to do it

  1. Lift your right knee toward your chest (the 'chamber') while exhaling sharply.
  2. Extend your right leg forward by snapping the foot out, striking with the ball of the foot while keeping the standing leg slightly bent.
  3. Quickly retract the foot back to the chambered knee position before placing it back on the floor.
  4. Inhale as you reset your stance and immediately repeat the movement with the left leg, alternating sides at a steady tempo.

Form checklist

  • Keep your torso upright; avoid leaning too far back as you kick.
  • Ensure the standing foot remains flat on the ground for maximum stability.
  • Maintain a high guard with your hands to keep the deltoids active and protect your balance.
  • Retract the kicking leg with the same speed and control used to extend it.

Pro tips

  • Focus on the 'chamber' phase; the higher you lift your knee before the kick, the more you engage your lower abdominals.
  • Imagine pushing through a target rather than just lifting your leg to maximize quadriceps and glute tension.

Make it harder

  • Increase the height of the kick to eye level to further challenge hip mobility and core strength.
  • Add a small hop with the standing leg as you kick to turn the movement into a plyometric exercise.
