Sled Drag - Harness

What it is

This is a powerful full-body movement where you attach yourself to a sled with a harness and drive it forward or backward across a surface. It primarily builds strength in your quadriceps, the large muscles on the front of your thighs. You will also engage your glutes, hamstrings, and calves for a complete lower-body workout. This compound exercise enhances power and endurance.

Technique tips

• Maintain a consistent lean into the direction of travel.
• Drive powerfully through your heels with each step.
• Keep your chest up and shoulders back throughout the movement.
• Focus on extending fully through your hips and knees.
• Control your breathing; inhale and exhale rhythmically.
• Start with lighter weight to master the movement pattern.

How to track your progress

Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
