Exercise guide

Backward Run

  • Intermediate
  • Compound
  • Timed hold
  • Lower legs
  • Upper legs

Backward running shifts the mechanical load to the quadriceps and calves while improving proprioception and knee stability. It provides a unique eccentric challenge for the lower body that balances out the repetitive stress of forward locomotion.

Setup

  1. Find a flat, clear path at least 20 meters long to ensure safety.
  2. Stand with your feet hip-width apart and a slight bend in your knees.
  3. Engage your core and maintain an upright torso with a very slight forward lean from the ankles for balance.

How to do it

  1. Push off the ball of your front foot and reach one leg backward, landing softly on your forefoot.
  2. Immediately drive off the ground with the landing leg to propel yourself further back in a fluid, alternating motion.
  3. Pump your arms vigorously in opposition to your legs to maintain momentum and balance.
  4. Maintain a consistent, rhythmic breathing pattern, exhaling forcefully during the drive phase of each stride.

Form checklist

  • Stay on the balls of your feet; do not let your heels strike the ground heavily.
  • Keep your chest up and avoid rounding your lower back.
  • Glance over your shoulder periodically to ensure your path remains clear.
  • Maintain a slight 'athletic crouch' with soft knees throughout the movement.

Pro tips

  • Focus on the 'push' rather than the 'reach' to maximize recruitment of the quadriceps and calves.
  • Keep your strides shorter and your turnover rate higher than a forward run to improve agility and control.

Make it harder

  • Perform the backward run on a slight uphill incline to drastically increase the burn in your quads.
  • Incorporate a resistance band around your waist anchored in front of you to add horizontal load.

Frequently asked

What muscles does the backward run work?
The backward run primarily targets the calves, glutes, hamstrings, and quadriceps, and also works the abs, hip flexors, and obliques as secondary muscles.
What equipment do you need for the backward run?
The backward run requires no equipment — just your body weight.
Is the backward run good for beginners?
The backward run is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
