Wanted to point out an easy way to hit DL and BS in addition to the DCs without killing yourself, because these two exercises are super important to be able to move heavy weight. If you're to the point where you can move 225 around on the DL with minimal effort, you really need to get going on this. The thing that makes these two lifts so vital is that improving them dramatically increases performance in just about every other freaking exercise out there.
Don't be scared to move some weight around. Get your form correctly with something like 135 and once you get this down you need to step it up. Maintain form and you should never hurt yourself. And furthermore, the more you do correct DL and squats, the stronger you will be with them and you'll have even less of a chance for injury. People get injured most often because they hardly ever do these and then try to get ahead of themselves too soon with poor mechanics. These lifts should not be dangerous. So that being said, get your mechanics down and start challenging yourself.
Grease Yourself Up
Since these particular exercises might not come up all the time, if you need to get your strength up, I suggest doing something similar to greasing the groove. We don't want to do so many that it will interfere with your DCs, but we do need to hit them more. Do this:
Monday: 1-2 sets of heavy/moderately heavy Deadlifts (with a weight you can lift no more than 6 times) after your warm-up and before you do the DC
Friday: 1-2 sets of heavy/moderately heavy Back Squats (with a weight you can lift no more than 6 times) after your warm-up and before you do the DC
DO NOT SKIP these even if your DC calls for a similar type of movement. Just take a little extra time between your DL/BS and the DC. Remember, you're not trying to waste yourself when you do this. You just want to stay on top of these lifts and keep trying to build yourself up.
Last thing: if you do this one day and the next day's DC doesn't agree with you, do it anyways. Life throws you unexpected things sometimes, and that's what we're preparing for.
