2016.10.05 - Birthday WoD

This one was an early birthday WOD, because Al wasn't there on his actual birthday. See if you can guess how old he turned. Everything is for time, so try to finish as fast as you can. The fastest time in class was 7:58, if you want a measuring stick.

As always, clean and jerks demand strict form. Even if you don't use heavy weight, you want to build the right habits. I've seen people get hurt with light weight, so don't get sloppy.

Exercises
  • Clean and Jerk

    Make sure you have a barbell with weight on it for this exercise; I usually see anywhere from about ~45lbs up to ~90lbs.

    To begin with, put the weight on the ground in front of you (this is different than the "high hang" where you start with the weight near your thighs). Squat down to grab the weights, but remember to face forward and keep your chest facing forward. Stand up, but as you do so, shrug your shoulders aggressively. I know it sounds silly, but it should be an *aggressive* shrug. You really want to build some momentum in that motion. However, keep your arms locked as you're doing this, or you'll end up doing more of a curl. If you need to make sure you've got it down, practice just that part of it a few times.

    The next step, starting from the shrugged shoulder position, is to quickly bring the weight up to about chest level and do a quick hop at the same time. If you were to watch the path the weight travels, it should be as close to your body as possible, and as close to completely vertical as possible. If the weight travels in an arc away from your body, you're doing it wrong. Your hands don't lift the weight as much as they adjust themselves to hold the weight differently. At the end of this motion, you should have your palms facing away from your body, as if you were "racking" the weight near your chest/clavicle.

    You can almost think of it as letting go of the weight in midair, and positioning your body underneath the weight so that you end up with your knees slightly bent and the weight at your chest. Don't actually let go of the weight, that can be all sorts of bad. However, you'll find that because it's a quick hop, you're pretty much jumping into it. At the same time, your hands will suddenly shoot up to hold the weight at your chest.

    As always, keep a good lumbar curve. You don't want to bend over as you do this. If you do it wrong repeatedly or with a heavy enough weight, your lower back will pay for it. Again, practice just the squat motion a few times so that it feels natural. That's the "clean" part of this.

    The last part, the "jerk" in the name, involves violently shoving the barbell directly over your head. Make sure that you're in a quarter squat position, then very aggressively press the weights directly over your shoulders. In fact, your momentum will cause you to do a slight hop while your hands go upwards. At the top of the rep, your arms should be completely locked out, and you should stand tall. Because this lets you use your legs to drive the momentum and the power, this should feel easier than a strict shoulder press.

    To finish the rep, you have to lower the weight to the ground safely (we're not allowed to just drop weights). From the locked out position at the very top, bring the weight straight back down to the racked position (resting on your shoulders/clavicle, palms facing away from you, elbows as high up as you can). From there, lower the weight to your thighs using your arms. Lastly, squat down to put the weight on the ground. You'll need to keep your chest facing forward the whole time; don't bend forward at any point. All of that is one rep. If you need to, practice the motion until it starts to feel natural; form is really important here.

  • Burpee

    It's a 5 step motion: 1) squat down & touch the ground, 2) kick your legs out into a push-up position, 3) do a push up, 4) jump back to the squatting position, 5) come up from squatting and jump 2 inches off the ground. Once it starts to feel normal to do this motion, you can start to make it a smoother motion by essentially dropping down into a push up position, rather than squatting and then kicking out your feet. It requires a little bit less energy, but it also requires more coordination and muscle memory.

    Scale down: Step back into the push up instead of jumping. Same goes for when you go back to the squatting position (step 4); step forward instead of jumping.

Happy CrossFitting.
