We're at the second last workout for the 2012 CrossFit Games Open and things just got a whole lot more interesting! Muscle Ups are my specialty, so we are going to give you this Breakdown raw and uncut! And it may not be obvious right away - but all those efficient Burpees you did in 12.1 actually primed you for the Muscle Up transition. Read on.
To get through this workout we really have to think about using a lot of skill to save yourself for the three different movements, and maybe even get a little recovering in for your shoulders during the Double Unders if we plan and prioritize properly.
1. Wall Balls - Check out KStar's 12.4 Prep and Mechanics video on MobilityWOD for proper positioning and mechanics to get through the 150 reps of Wall Balls.
2. Double Unders - Review our entire series on Jump Rope Double Unders on GymnasticsWOD (http://gymnasticswod.com/progressions?field_tags_tid=29&field_tags_apparatus_tid=71). If you focus on good positioning while you are able to keep your upper body relaxed, this is where you can recover a bit to prep for some Muscle Up work. Have your wrists take care of the rhythm with the rope, and practice it with a folded rope until you get that skill nailed down.
3. Muscle Ups - This movement does require a lot of upper body strength to pull up and then to press out of the dip, but you do have an opportunity to use your hips and apply a lot of skill as the assistance to transition and even with the dip. As your warm-up, practice the 5 progressions demonstrated in the video and get the motor pattern down: 1) Hollow Body to Hip Extension, 2) Global Extension to Sit Up, 3) Dip Balance, 4) Hollow Body to Forward Roll, 5) Kipping Dip.
If you are having trouble with the Hip Extension and snap to Sit Up, go back to our 12.1 Breakdown minute 6 (http://www.youtube.com/watch?v=sWwbovT-rz4) - what does that efficient Burpee look like? Yes - it's the same movement we're doing for the Muscle Up transition on the rings. For the efficient Burpee we're just doing it on the ground where we start with the hip extension, then hip drive to snap the feet in. Same thing on the rings - arm straight, global extension with butt on, then transition by snapping the hips close and bringing your nose over the rings to your toes. Try a few reps of efficient Burpee again, get to know how that feels and what the motor pattern is, and then try it on the rings on you've pulled and/or swing up to the right height.
