Hey LisaM....

What is wrong with leg extensions if done properly ( slowly w/o jerking) and you dont lock the knee? Followed, of course by leg curls or other exercises for the hams.

I know this is directed to Lisamarie, but if I may:

There is nothing wrong with leg extensions done properly. Most of the advice against this exercise is directed to people that have had knee problems, knee surgery or weak knees that are suceptible to injury.

In principle the exercise is no different than tricep extensions. But people that have elbow problems (or past surgery) may have to avoid this exercise alltogether.

Irul, the simple answer is nothing IF you do not have any damage to the knee, or tenedency towards knee damage.

Check out the thread on the ACL. There is an explanation of shearing forces on the knee, as well as the benefits of closed chain vs. open chain exercise.

There are in fact some orthopedists, PTs, etc. who believe that nobody should do leg extensions. This has to be a personal choice.

Now the important issue. Is this a really good exercise for skiing?

Not really. The leg extension is a total quadricep isolation. Isolated muscular contraction is actually counter intuitive to sport activity.

When performance is optimal, muscles are working together in an integrated manner. If the body trains itself to isolate the quads, you are giving extra work to a muscle that's already overworking.

Now here's the "geeky" stuuf. Since there have been some complaints, and even an entire thread that may or may not have been an attempt to make fun of the way I intellectualize everything, let me try to simplify this.

There is a difference between the way you train for esthetics, and the way you train for sport. Is there some carry over between the 2 methodologies?
Of course!

But if you are looking for optimal perormance, an integrated training program will usually work best. So for sport, the training needs to happen more at the neurological level, not just at the muscular level. {Keep in mind that body building would be the exception to the rule}

In plain English, for sport you want to think about movement patterns, where the muscles work together. That's why squats, leg presses and lunges are usually recommended. A bunch of ski specific muscle groups are working together.

Hope I did'nt get you even more confused.

Once again, people answered in one sentence what took me a bunch of paragraphs.

do 'em. in moderation and in conjunction with ham curls.(stabilizing the knee "capsule.") i'd recommend lighter weights, higher reps; if ya wanna bomb heavy, leg presses. no "cheating" movements.

RuBlo, no true mullet wearer would "like" his malt liquor. Nope a true mullet guy "likes" his malt liquor as in "I likes my malt liquor"

This is usually said while errr 'reclining' in the gutter near his truck.... :
