Notably, this is the first time that pistol squats (one-legged squats) have appeared in the Open. What an unpleasant surprise!

CrossFit Open Workout 20.4: Equipment & Gear

Equipment needed:

  • Box of appropriate height for your division (the top of
    the box must be at least 15-by-15 inches)
  • Barbell – Use a bearing bar if at all possible – the smooth spin makes C&J easier.
  • Standard bumper plates (18-in. diameter) to load to the
    appropriate weight for your division
  • Medicine ball (scaled divisions)
  • Collars to secure the plates on the barbell

Optional:

  • Lifting Belt – a low-profile Olympic weightlifting style belt is going to help in this workout. You can see from the pictures that Ben Smith put one on for the heaviest cleans.
  • Lifters – Weightlifting shoes may help especially in the pistol squats – but also for the clean and jerk. Sean Sweeney donned a pair of “lifters” for his final heavy rep.
  • Knee sleeves – Tight fitting, neoprene knee sleeves may be helpful for the high repetition cleans.
  • Wrist bands/Head Bands – as with every competition workout – there’s a lot of sweat that can mess with your grip.

Box jumps are required for CrossFit Open Workout 20.4 – but we recommend stepping up or down to reduce the rebound stress.

CrossFit Open Workout 20.4 Strategy and Tips Guide

Here’s some 20.4 tips and tricks to get your best score possible:

  • This includes 90 reps of Box Jumps – this is a lot of volume early on – so establish a conservative pace. Step up or step down for all reps as high repetition rebounds have caused achilles heel tendon issues in past events!
  • Similarly, there’s a lot of single leg squats/pistol squats. Ben Smith commented that this made the clean and jerk that much more challenging.
  • For the clean and jerk – use the form that allows you to most efficiently do the rep. This means avoid a full squat clean until you must use it. Power cleans and split cleans are permitted.
  • Hook grip is recommended for the clean and jerk – especially considering the high volume in a short time period.

Good luck!
