FAQs About Leg Extensions vs. Leg Curls
Is leg extension the same as leg curl?
No, leg extensions and leg curls are two different exercises that target different muscle groups. Leg extensions involve moving your lower leg against a weight or lever to extend the knee joint, whereas a leg curl involves bending your lower leg to flex the knee joint. While both exercises strengthen the legs, they have slightly different functions.
Should I do leg extensions or hamstring curls first?
It depends on your goals and what type of workout you want. If your focus is hamstring development, it's best to start with leg curls. If you're focusing on quad development, then you should start with leg extensions. To make sure you’re getting the most from these exercises, pay attention to proper form.
Are leg extensions worth it?
Yes, leg extensions are definitely worth it. They target your quadriceps to build strength and size. They can be used as part of an overall workout plan or simply as a standalone exercise for anyone who wants to isolate their quads.
Are leg extensions as good as squats?
No, leg extensions are not as good as squats when it comes to overall lower-body strengthening. While leg extensions can help build strength in the quads, they don't work the hamstrings and calves as squats do. Squats also work multiple muscle groups at once, which provides a more comprehensive workout for the entire lower body. That being said, leg extensions are still a great exercise to include in your routine, as they can help you focus on your quad development.
