    When I go to the gym, I see guys doing exercises where they are rocking their body (ex...standing curl) and wondered if that's how the exercise is really done or if they are using too heavy of a weight. Personally, I don't do it myself and try to keep my back upright otherwise I go to a lower weight if I feel like I'm rocking. Just trying to see if I'm possibly missing out on something??

    A little rocking isn't bad, sometimes your going to have to sacrafice form to a certain extent to get bigger.

    I've always had trouble with my bicep, because I was very strict with my form, but ever since I "rock" a little, not too much, they have gotten bigger.

    Generally, rocking your upper body back and forth during exercise is bad posture and form. It`s using the body to partly help the arms. It`s not fully exercising that muscle/group. This is the value of machines-they isolate and make that muscle work fully.

    If you can`t do a standing curl without it, the weight`s too much.

    Good practice and form will stand you in better stead long term(injury prevention, for example) than bigger muscles.

    I think rocking takes away from muscle isolation, which is what I prefer. I know the big guys do it because of their plateau at certain weights or even as part of a compound exercise. My main issue is when the uninformed or newbies start to copy the big boys, that is when injuries start to happen.

    for me it is about muscles isolation, proper breathing and squeezing on the peak. If I am working out my bicep I only intend to target my bicep and not waste my energy on swinging my whole arm. Swinging the arm, aka rocking, also can lead to the entire lift being due to the momentum of the swing.

    this is just my opinion and I am not a professional. yet.
