Snatches and burpees eh. Cake work. This is the workout where all your work on efficiency and technical value should pay off. The body will always fall on it strongest points and movement patterns under fatigue. Certainly after 70 or 90 burpees fatigue will begin to set in. At this point your score will reflect the months of training you have completed prior to now. If you’re barbell work was just something you got through and not something you spent time focusing on then your snatch technique will show that. However if you spent the time and focus on good technique, did lighter weights well to allow for the training of good movement patterns, and took the Olympic lifts seriously now is your time shine. Under fatigue your body will fall on what it knows best and ultimately will fall on the habits you’ve created. Hopefully you’ve created good habits and have created strength in good movement patterns. If you have you’ll see that work pay off. Snatches and burpees… Good luck!
