How to do it

Seated leg curl. Greater hamstring stretch than the lying version.

Muscles worked

Mainly isquiotibiales. Train it inside a balanced routine to progress safely.

Recommended sets and reps

As an isolation exercise, it works best in 3–4 sets of 10–15 reps with 0–2 RIR. Use it at the end of the session to add volume without systemic fatigue.

Common mistakes to avoid

• Rounding the lower back when hinging: the movement should come from the hips, not the spine.
• Using too much weight at the cost of technique and full range of motion.
• Doing reps too fast, without controlling the eccentric (lowering) phase.

Alternative exercises

• Lying leg curl
• Standing cable leg curl
• Romanian deadlift
• Single-leg RDL
• Glute-ham raise
