Anyone heard of this so called "BLD" theory? The bi-lateral deficit, where it states that a person is not getting top notch energy/strength when doing movements with both arms/legs as opposed to working each seperately? (uni-laterally)? I just read an article that was actually posted in another thread here on t-nation about filling out seperate muscle groups and part of them for those with longer limbs, here is the link to the article. http://www.t-nation.com/findArticle.do?article=07-bonus-006 As soon as I read this I kept telling myself ? You're going to tell me you can push more weight with legs for say LEG PRESS or Extension uni-laterally? No. I dont buy it. You are using more effort BALANCING your body for unilateraly exercises than the deficit of a bilateral movement. What are your guys thoughts? Other than an exercise like Lunges which is inherently a unilateral movement ofcourse.
