Today Connor DL'ed a 8KG KB for reps. He'll be 3 in July. I was pretty surprised because he was telling me he wanted to workout with daddy, so I placed the KB in front of him and up it went. Out of curiousity I gave him the 12KG KB also and he did a couple of partials with that.
He's around 36lb's so 8KG's is just around 1/2BW.
Pictures to be added later.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
