The prone floor curl lies face down and curls your heels toward your glutes using just bodyweight resistance, providing hamstring isolation that requires no equipment at all. This simple movement trains knee flexion anywhere—hotel rooms, parks, or at home—making it the most accessible leg curl option available.
When to use it
Use for home workouts or when equipment is unavailable.
Who it's for
All levels needing no-equipment hamstring work.
Lie face down with legs extended and hips pressed into the floor. Curl your heels toward your glutes while keeping your hips down. Squeeze your hamstrings hard at the top, then lower slowly. Add ankle weights when bodyweight becomes too easy.

Common Prone Floor Curl mistakes
Lifting hips off the floor during the curl.
Losing hip position during the Prone Floor Curl shifts the loading pattern away from your Hamstrings (biceps femoris) and can compress your lower back. Stay planted and let your Hamstrings (biceps femoris) do the work.
Using momentum to swing legs up.
Bouncing or using momentum during the Prone Floor Curl takes work away from your Hamstrings (biceps femoris) and puts your connective tissue at risk. Control the weight through the full range — if you can't, lower the load.
Not achieving full range of motion.
Cutting the range of motion short on the Prone Floor Curl means your Hamstrings (biceps femoris) never reaches full stretch or full contraction. Research shows full range of motion produces significantly more muscle growth than partial reps at the same load.
Relaxing hamstrings at bottom position.
On pulling movements like the Prone Floor Curl, this mistake typically means your arms are doing work that should come from your Hamstrings (biceps femoris). Initiate every rep by engaging your Hamstrings (biceps femoris) first, then let your arms follow.

How to Program the Prone Floor Curl
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 15-20 reps. Rest 45 seconds.
