When one reaches a certain lvl, yea id say loose form can have its advantaged. But at the early to moderate stages, id still argue that one should stress form.
I cant say that i like this thread, simply because its going to give a lot of newbs that read these boards the impression that not fully extending their arm and swinging their entire body in an attempt to curl a weight is perfectly acceptable.
Truth is, there are three types of form- Bad form, Good form, and Perfect form.
Bad form is you not knowing what youre doing. It is you shortening ranges, contorting body parts, and essentially wasting space in a gym.
Good form is text book form. Self explanatory.
Perfect form is what is ideal for you. It changes with the person. It fits your body type and your needs to give you the best possible firing in a muscle. This is developed through years of training and experience and takes a bit more understanding of THE body and YOUR body.
Chances are, most people should stick to Good form for a few more years before they attempt to bend the form rules.
I tend to agree with this comment.
I’m also a lot more “strict” with my form now that I’m at a more advanced stage than I ever was before. For me, loose form generally means the MMC is not as strong and you are not feeling the muscle work the entirety of the movement, it becomes a game of momentum. I guess I believe that a good stretch and squeeze is imperative to have in every exercise, especially something like back training. Doesn’t mean I won’t go as heavy as possible but I don’t use much body english anymore.
