When I first start doing lat pulldowns in an HST cycle, I lower the bar till it touches my chest. The weight is light enough that I can do that pretty easily. Towards the end of my cycle, I reach a point where I can no longer do this. I figure that's not so bad--only a small part of the range of motion is being lost. There are many exercises like this: as the weight gets higher and higher, you can't quite complete a maximum range of motion. What I'm wondering about is the possibility of overtraining due to this fact. For example, if you can't quite complete the full range of motion, that doesn't stop you from *trying* to complete it. As you struggle to get that last 5-10 percent of the range of motion, you're essentially pulling/pushing on a weight that won't budge, which is (as I understand it) hard on the CNS. It's easy to say "always complete 100 percent of the range of motion", but in many cases, I'm not clear that you get an enormous hypertrophic benefit from that last 5-10 percent of the motion. (Once you start sacrificing 30 percent, yes, you're losing a lot.) Is this a legitimate problem, and if so how do people here deal with it? Thanks.
