Brian ... My programs and classes do A LOT of loaded carries. Personally, I go through my phases ... my own program is very freestyle, so it trends, but the specifics change pretty often. When I do perform loaded carries, its basically farmer's carries, double waiter's walks, and long ruck marches. Prowler pushes get in there sometimes. Often, I can't say ... but how much: always heavy. My lightest farmers carries are two 40s. Double waiter's walks are 32s - 40s. And you can get nuts on the prowler. The goal is to posture properly and load up enough to slow you down ... but not that slow. It's an art, but don't feed the ego. My ruck usually has 50-65lbs in it - 90min-3 hours distance, at least twice monthly.
Marchese ... thank you, and you're welcome. I really don't feel any of what you mentioned while the bell is moving ... but I used to. This comes with practice, but the longer you swing, the less you need to feel, if that makes sense. Everything seems to happen automatically ... planking tight against the bell, I only think "glutes". Throwing it back down, I only think "wait for it". The bell hits a spot on the way down when I feel one with it - this is about arms-to-ribs, or whatever cue is out there. At this point, I violently drive back to hit the aforementioned position, then pull the trigger and, wham ... I'm in the plank again. One in about 20 swings is off a bit, and I always think, "how did that happen?"
The best thing about a properly performed swing is getting to be violent without serving prison time.
