Frequently Asked Questions

1. Is leg extension or leg curl better?

Leg extensions primarily work the quadriceps muscles. This is the muscle found at the front of your thigh. If you’re looking to increase size in your quads, or want to define that “teardrop” section, leg extensions are your go-to exercise. Conversely, leg curls work the hamstring muscles.

2. Is a leg curl machine worth it?

A quick explanation: The leg-curl machine targets your hamstrings because it requires you to flex your knees, one of the jobs of your hamstrings against resistance. So as leg curls go, it’s a far better choice than the machine version. But here’s the best part: It’s also a great core exercise.

3. Do leg extensions build mass?

Leg Extensions Useless for Building Muscle? This is false. As already stated, when it comes to EMG activity, it’s been shown to be some of the most beneficial movements to isolate the quads. The flak you may hear comes into play due to people utilizing machines over compound (multi-joint) movements.

4. What muscles does the leg curl machine work?

Leg curls target the hamstrings (biceps femoris, semitendinosus, and semimembranosus) and calf muscles (gastrocnemius and soleus muscles). When lowering your feet back down, your buttocks (gluteus muscles), thighs (quadriceps), and front of the shins (tibialis anterior) are activated too.

5. Are leg machines bad for you?

Exercise machines were invented to provide a safe alternative to free weights, but sometimes they’re anything but. As a matter of fact, they can put your body into unnatural positions and take your joints through dangerous ranges of motion. Over time, this can lead to muscle strain and even serious injuries.
