I was just thinking, could there be more this dynamic and isometric tension then we think? i only bring this up because ive noticed on myself muscles that shouldn't be getting worked doing what i'm doing are growing and the only thing i can think of is somebodys slipping me drugs or the simple act of flexing to keep stability during an exercise can actualy strengthen muscles. if you think about it, it's really not all that crazy because what happens when you force against resistance. your muscle makes a tension level based on the load being put on the muscle. now are we actualy capable of making our own muscles contract to a tension level that would actualy cause strength gain? i know i don't know, do you? do a little test for yourself. turn your chair to the side away from your computer and while sitting, flex as much as you possibly can and do some air bench pressing while sitting in your chair. as i wrote this, right after that last scentance, i tried to do as many as possible flexing to absolute maximum i could attain through the whole motion. i don't know how many you can do, but flexing as hard as i can doing the air benchpress i was only able to do 12 untill my form went to shit and my muscles were screaming. i'm intriuged anyways, i'm going to experiment with this and report back. i know that this used to be an old bodybuilding trick but i want to see if it has any implications at all for strength gain. i'm going to try it while doing my bodyweight routien and see what happens. Can you even contract to the point of cns breakdown? only one way to find out! EDIT:lol i just did air shrugs, and there is definate workout fatiuge. i don't know more experiments are needed. Anyone willing to devote some time and try this with me? EDIT: a simple way to get you max contraction is to imagin your moving a bar with 8 or 10 plates. LMAO OMG AIR DEADLIFTS!!!!!!! LMAO (ps i'm joking about that last one) i think i'm loosing my fucking mind edit: or am I? hell if your tallented anough to max flex all the muscles used in a deadlift at the same time while doing the movement go for it.
