I don't know what's the benefit of having strong and muscular legs before and during leg lengthening. I'd say flexibility is the most important thing and that's compromised if you work out your legs with weight training.
yes guichet says that....but three doctors I have talked to (Monegal, Birkholtz, Betz) plus Betz's PT say it's not good to have very muscular legs. The more muscle you have the harder it's to stretch.
I don't know if you go to the gym.. But have you ever missed the gym for several weeks, but then go back and have a ripper workout? I mean you really smash yourself? After just a couple of weeks your muscles become lazy and sensitised to stress.. Let's say you worked your legs. 24-48 hours later you will barely be able to walk. I mean, you'll be in so much pain that you'll struggle to squat onto the toilet.
If you maintain your strength, endurance AND flexibility, your muscles will become used to the stress. They will be desensitised from the trauma.. If you go into your surgery with your legs in peak condition, they'll be less susceptible to pain because they're already put under constant stress. Why do you think that Guichet's patients are able to lengthen so fast compared to patients of other doctors.. If you have a regular Joe going into surgery without the proper preparation, they're going to experience more pain, more issues with stretching of the soft tissues and have a much harder and longer journey in general.
It makes perfect, logical sense why you should prepare for the surgery.
