Standing Leg Curl

Muscles worked

Main muscles
- Biceps Femoris (Long Head)
What it is
This exercise targets the hamstrings, the powerful muscles on the back of your thigh. Using a specialized machine, you will curl one leg at a time against resistance. It’s an isolation movement designed to build strength and definition in these muscles. Focus on controlled movement to maximize muscle engagement.
Technique tips
- Maintain a forward-bent torso throughout the movement.
- Position the pad just below your calf, not behind your ankle.
- Keep your upper thigh firmly pressed against the machine pad.
- Curl the weight with control; avoid using momentum.
- Exhale as you curl the leg up; inhale returning to start.
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.
