Seated Lean Back Cycling On A Chair

  • Beginner
  • Compound
  • Rep-based
  • Lower legs
  • Upper legs
  • Waist

This exercise targets the lower abdominals and hip flexors while improving core stability and leg endurance. Leaning back increases the tension on the rectus abdominis, making it a more effective core-focused variation of standard seated cycling.

Setup

  1. Sit on the front edge of a sturdy chair or flat bench with your feet flat on the floor.
  2. Grip the sides of the seat behind your hips for stability and support.
  3. Lean your torso back at approximately a 45-degree angle, keeping your spine straight and chest lifted.
  4. Lift both feet off the ground, bringing your knees toward your chest to find your balance point.

How to do it

  1. Extend one leg straight out in front of you while pulling the opposite knee toward your chest in a fluid cycling motion.
  2. Exhale as you switch legs, driving the bent knee in and fully extending the other leg without letting it touch the floor.
  3. Maintain a steady, rhythmic tempo, focusing on a controlled 'pedaling' movement.
  4. Continue alternating sides smoothly while keeping your core braced and your torso completely stationary.

Form checklist

  • Keep your lower back flat or slightly arched; avoid rounding your spine.
  • Maintain the lean-back angle throughout the entire set to keep tension on the abs.
  • Ensure the movement comes from the hips and knees rather than rocking the upper body.
  • Keep your neck neutral and your gaze fixed forward to avoid strain.

Pro tips

  • Focus on the 'pulling' phase of the cycle to maximize lower abdominal engagement.
  • Point your toes to further engage the quadriceps and create a longer lever for the core to stabilize.
  • Squeeze your shoulder blades together to prevent your chest from collapsing forward as you fatigue.

Make it harder

  • Remove your hands from the chair and hold them straight out in front of you to significantly increase the balance challenge.
  • Slow down the tempo, holding each leg extension for two seconds to increase time under tension.
