Step by step instructions, muscle activation and variants for the Standing Single-Leg Curl.
The Standing Single-Leg Curl is a unilateral hamstring isolation exercise performed on a standing leg curl machine. By working one leg at a time, it helps correct strength imbalances between limbs and provides a strong hamstring contraction through a full range of motion.
The Standing Single-Leg Curl is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
