@dkeefe Sounds foolish but the first thing that really stuck out years ago was far increased stability at rowdy concerts, I'm a large man anyway but getting knocked off balance became non existent. I'm old now so I don't do that much anymore.
After I had been doing kettlebells and bodyweight for 5 years ish I decided to take a stab at bench/squat/dead and found not only was I more stable on the squats and deads, I hadn't regressed a lot in my max lifts. My deadlift form greatly improved on its own, I had always tended to hump my back a bit prior to kettlebell training and post I've found I can keep a very straight back and posture.
Last year I was very focused on s&s the first part of the year, and then decided to hop back into the Highland games. My numbers didn't get back to when I was active(mostly due to being out of practice), but I felt really good and aside from a bicep repair over the winter I'm expecting more improvements this year. Especially on weight over bar and hammers. This is basically on swings, cleans, tgus, and presses, with some erg rowing.
