Approach today's WOD as an experiment:
Mentally - how long can you keep going without stopping? If you take a break, look at the clock and make a mental note. Also record how many stops you took that lasted 3 seconds or more.
Nutritionally - what's the minimum you can eat to provide ENOUGH energy? You don't want to come into this one full or bloated.
Setup - are you better to drop fast to a soft surface (green/yellow mat) or have a hard surface to push off from?
Movement - there's a bit of flexibility here. Do you jump your legs in or out?
My thoughts:
Mentality - you don't need to stop. Change is as good as a rest. You can slow down, and drop to your knees, walk your hands out to a pushup; you can jump your feet in narrow or wide. Just keep going. Pick a target number and start counting backward when you get halfway.
Nutritionally - at 7 minutes, you're unlikely to really dip into fat reserves, making carbohydrate intake more critical today. Protein will be necessary only for blood glucose buffering. Too much carb will pull water into your belly. Just eat normally (for me, that's Zone.)
Setup - if you can jump your feet wide, and land on your heels, your hips (hamstrings/glutes) will propel you upward, and you'll only use larger joint angles, saving your quads. I'd only start jumping inside my hands when my arms/chest are tired, so that the upper body doesn't have to push off as hard.
The rest is optional, but this is critical: you must be in an AEROBIC mode when you start. That means you should be sweating (and not just from nerves) before you start. Your body has to be metabolizing energy in the right pathway when you get rolling, or you'll bonk. Run, skip, row; spike your HR, then recover as you roll out and stretch. Stay warm, and then hit it.
I'm also going to try to do this workout with someone who's faster than me at burpees: Andrew or Mac. I'll use them as rabbits. Sorry, lighter folks, but the pressure's on YOU here! haha.
