Dave Castro Warns Us About The 2017 CrossFit Games Open
That right there is pictures of dumbbells. Specifically, pairs of 35s and pairs of 50s with a simple message: "You've been warned."
I think it's safe to assume that CrossFit HQ doesn't care at all about the logistic limitations of how many pairs of 35s or 50s various affiliates may or may not have and will be including dumbbells in the Open this year.
If you wanted to purchase the exact same weights included in that photo that Dave Castro posted, you'd spend $1396 + taxes + shipping:
And that doesn't include the dumbbells you'd need for the various scaled versions of whatever workout this may be.
A few days ago, Castro posted a video of Brooke Ence performing a Turkish Get Up with a barbell which could also be a hint that HQ expects all affiliates to have the space for multiple people to perform TGUs with judges near them.
Be sure to get your permits in line for the swimming pools you'll have to build for the water event in the 2018 Open.
