I just got done doing interval sprints on the rower from hell (thats the one in my garage that I brought home from the 2009 Crossfit Games in Aromas. We have a love-hate relationship)
Anyway, during that 30 seconds "on" I'm trying like he...ck to perfect my haystack** and the only way it gets even close to what I'm looking for is if I "turn on my belly" and tighten my core.
I can produce a beautiful haystack at lower power outputs but I struggle during max effort pulls. I though I could hold it together for 30 seconds but I'll tell you, I'm smoked.
What does this mean for a workout that requires longer than 30 seconds? Probably that my middle isn't strong enough to hold it together. And if it's not, my spine is at risk. And my spine is already all kinds of sideways.
I know midline stabilization is a big chink in my armor, and one that I need to address before disaster strikes. It's also something I suck at so I avoid it at almost all costs. (I know you have these, too)
There's nothing we do that won't be improved by turning on your belly, tightening your core, contracting your midline. There are a gazillion ways to say it, but activate those abdominal muscles in everything you do and you'll be better for it. Your spine will love you.
And if you lack the ability to turn them on, we've got strategies for you. Just ask.
**your haystack is your force curve on the C2 monitor. If you have no idea what I'm talking about, check the website over the weekend. I've got more FUN brewing)
