Single-Leg Leg Extension primarily targets the Quadriceps. This makes it an effective strength exercise for building quadriceps development.
You will need a machine to perform the Single-Leg Leg Extension. Make sure the equipment is set up properly and at the appropriate weight before starting.
Yes. The Single-Leg Leg Extension is a beginner-friendly exercise. Focus on proper form before adding weight or intensity. It's a great movement to include early in your training.
The Single-Leg Leg Extension is an isolation exercise that focuses on a single joint and muscle group. Isolation exercises are useful for targeting specific muscles, correcting imbalances, and adding focused volume. They are typically performed after compound movements in a workout.
For strength, aim for 3-5 sets of 5-8 reps with heavier weight. For muscle building (hypertrophy), try 3-4 sets of 8-12 reps at a moderate weight. For endurance, use lighter weight and perform 2-3 sets of 15-20 reps.
Good alternatives include the All Fours Quad Stretch, Alternate Leg Diagonal Bound, Backward Drag. These exercises target similar muscle groups (Quadriceps) and can be substituted based on available equipment or training preference.
Best for: Building practical strength and adding focused work for Quadriceps. Use it when the movement fits your goal, equipment, and recovery.
Programming tip: Start with a load you can control for every rep. Add reps before adding weight, and keep the last rep clean enough that you could repeat the movement next week.
Common mistake: Chasing heavier weight before the setup, range of motion, and tempo are consistent. If the rep changes every set, the log stops telling the truth.
Track it: Log weight, reps, sets, and one short note about form or difficulty. Over time, those notes explain plateaus better than motivation quotes ever will.
