One thing we are seeing from the kettlelbell swings in today’s workout was placing(more like dropping/releasing) the kettlebell down poorly when someone completed their set (it was only 7 swings for today’s WOD people). We spend a lot of time talking about picking the kettlebell up with a flat back but it should be returned to the floor that way as well. If you let the weight carry your chest to the floor and loose your flat back you are putting your spine in a compromised position.
We are also seeing people slam the bell down in exhaustion and we definitely want to avoid that. The bells can bounce and it would be terrible if someones toe or foot was broken from an errant throw. Your safety is of utmost importance to us as a coaching staff.
