The standing single leg curl is a hamstring exercise performed standing on one leg while curling the other heel up toward the glute through knee flexion. Without weights, the bodyweight load is light and the exercise functions primarily as a hamstring activation drill or warm-up rather than serious strength work. With ankle weights or a resistance band, the exercise becomes a real hamstring strengthening tool. This exercise sits in the foundational hamstring training category — accessible to beginners, useful as warm-up activation, and adaptable through added resistance. The standing position trains balance alongside the curl motion, providing dual benefit. For older adults, beginners building lower-body strength, or trainees warming up before more demanding hamstring work, the standing single leg curl earns a useful niche. The trade-off versus more demanding hamstring exercises (Romanian deadlifts, inverse leg curls) is the modest training stimulus without added resistance. Pure bodyweight standing curls won't drive serious hamstring development. With ankle weights or bands, the exercise becomes more productive but still doesn't match the loaded compound exercises for strength building. As warm-up activation or beginner introduction, it provides genuine value; as a primary hamstring exercise for advanced trainees, it's outclassed.
Why train the Standing Single Leg Curl?
- Provides accessible hamstring activation for beginners or warm-up purposes.
- Trains single-leg balance alongside the curl motion.
- Suitable for older adults or those returning from injury.
- Adaptable through ankle weights or band resistance.
- Pairs with squats and lunges for foundational lower-body programs.
- Useful in equipment-limited contexts (no machines required).
How to do the Standing Single Leg Curl: step by step
- 1Stand with your feet hip-width apart and your hands on your hips.
- 2Shift your weight onto your left leg and lift your right foot off the ground, bending your knee.
- 3Slowly curl your right heel towards your glutes, squeezing your hamstring.
- 4Pause for a moment at the top, then slowly lower your right foot back down to the starting position.
- 5Repeat for the desired number of repetitions, then switch legs.

Common mistakes to avoid
Bouncing through reps
Slow controlled curls produce activation. Bouncing reduces engagement.
Leaning the body forward
Stay upright. Forward lean shifts work to other muscles.
Cutting range
Curl as far as comfortable to maximize the engagement.
Using only this exercise for hamstrings
Without added resistance, this exercise is too light for serious hamstring development. Pair with Romanian deadlifts or inverse leg curls for strength building.
Skipping the standing leg's stability work
The supporting leg trains balance. Don't lean on a wall or hold heavily — use light support only.
Easier and harder variations
Easier
Hold a wall or sturdy support for balance. Or perform with both feet on the floor and just curl one leg lightly.
Harder
Add ankle weights (1-5 lbs) or resistance band looped around the foot. Or progress to inverse leg curls for serious hamstring strength.
Alternative exercises
Romanian deadlift
Standing hamstring work with weight progression. More productive for strength building.
Inverse leg curl
Advanced bodyweight hamstring exercise. Significantly more demanding.
Glute bridge
Hip extension hamstring work. Foundational alternative.
How to program the Standing Single Leg Curl into your training
Standing single leg curls work as warm-up or accessory work. Sets and reps: 3 sets of 12-20 reps per leg with 30-60 seconds rest. Frequency: 2-3 times per week as accessory; daily as warm-up. In a session: as warm-up before main lower-body work, or 3 sets of 15 reps as accessory after squats. For general fitness: 2-3 times per week. Don't expect serious strength gains from bodyweight version alone.
Recovery and frequency
Minimal recovery cost. Daily training is tolerable.
Frequently asked questions
How many sets and reps?
3 sets of 12-20 reps per leg.
How often?
2-3 times per week as accessory; daily as warm-up.
Will this build hamstrings?
Light without resistance. Add ankle weights or bands for productive training.
Is this for beginners?
Yes — accessible introduction to hamstring training.
Should I add resistance?
Eventually, yes. Ankle weights or bands transform this from activation to real strength work.
When should I progress?
Once 20 reps feel easy and you're ready for more demanding hamstring work, progress to inverse leg curls or Romanian deadlifts.
