    Question Are Legs Extensions and Hamstring curls worth it?

    Are leg extensions and hammy curls actually any good for adding mass?
    I've just asumed they probably arent so just stick to squats, deads and lunges.

    Are they worth doing?

    Yes.

    They're better for hypertrophy than for strength. That being said, you're never wrong sticking with Squats and DL's! You might try throwing them in at the end for the pump or to exhaust them completely. A Leg extension strip set or 2 is brutal after Squatting

    If you are properly using them to supplement other leg work they can be pretty effective.

    You don't have to do them at all provided you have a well-rounded program. I didn't do leg extensions or hamstring curls for 18 months, but made good progress regardless. IMO, once you have made a great deal of progress and have a spectacular set of wheels, you may want to further sculpt them with isolation work but most people are far far away from that point. I will probably never do leg extensions (barring injury), but I do hamstring curls every once in a while if I don't feel like doing Romanian deadlifts.
    Use the tools of the trade to help you. I use devices such as chalk for grip strength, gloves, wrist straps, lifting belts - if it helps you lift more, it's all good. - Ronnie Coleman, Hardcore, 2007 Triumph Books

    Biggest question in bodybuilding: Whaddaya bench? As I've said before, it doesn't matter how much you bench; it matters how much you [i]look[/i] like you bench... There's no round on stage that's the benchpress round. - Bob Chicherillo, World Class Physique, CMG

    I say yes. For one, they are a way to continually overload the muscles w/o equally challenging your nervous system, as we do with compounds and heavier exercises.


    The leg curl is especially valuable, due to the motion being at the knee and not the hip, as is opposite with most of the compound hamstring dominant movements. About the only other option is the GHR.

    You can add mass (provided you've got the other prerequisites right) with most exercises and that includes leg extensions and curls.

    If however you want to get stronger at the squat, you're just going to have to squat.
    This is what I've been doing lately: squatting heavy, squatting often and not too much other leg work (no machine use whatsoever) and progress has never been better.
    Strength + Speed = Power

    If you never fail, you aren't truly pushing yourself to the limit. If you never push yourself to the limit, how do you know what you're truly capable of?

    I always preferred the knee curl more than the knee extension, didn't feel as odd. Kind of like how elbow extensions kinda hurt sometimes but not really with elbow curls.

    Every isolation exercise does as advertised, increases the mass of the targeted muscle.
    They are also great for creating imbalances, especially if overdone.
    The lower weights used on isos give people the impression they're wasting their time but that's the whole point, to only use as much weight as a single small muscle can handle.
    The muscle will respond if worked.

    If you are looking at it from a bodybuilder's perspective, then curls and extensions are a must. For proof you need look no further than the best wheels in the game. Take a look at Tom Platz and Branch Warren's leg day routine.

    They do extension and leg curl routines that would leave many of us crying like a girl.

    (No offense intended towards girls, but let's be honest, some of you do cry a lot.....)

    I stopped doing them long time ago. Only DL and Squats now - and running if that counts -. But i am far more interested in functional strength than in looks.
    The only reason i keep wondering from time to time about doing some leg curls is because i feel like i usually target more the quads with my routine than the harms. But im pretty sure that i wont touch the leg extension in long, long time (if ever).

    In what respect? You can create imbalances doing compounds too, so I don't see any reason to single this out. Think of the guys who broly bench and rarely row, same troubles.

    But the knee extension is functional if you are ever sitting in a chair and you want to kick your feet up and have a chick sit on your shins right?

    Yeah I know what you mean, hams are more dynamic stabilizers during squatting and people with good glute activation may be using them as the primary extensor during deadlifts too.

    The leg extension machine is good, especially when you use a cable machine for this. The KNEE extension machine, on the other hand, I would agree about.

    Pro tip: the leg press is a leg extension machine
