have spent a lot of time around kettlebell enthusiasts and am married to a SFG kettlebell instructor. Kettlebells are too cumbersome at even moderately heavy weights to be a useful tool for strength training

俺の回りにはケトルベルの信奉者がたくさんいて、女房はSFGインストラクターだけど、贔屓目にみても時間の無駄だね

Very heavy, low-rep swings might be useful for something similar to dynamic effort sets, but power cleans are better,

パワクリーンやればいいだけのこと

My wife says, if you want to get strong stick to basic barbell training; if you want to build your conditioning do high intensity intervals with a sled; if you want to do kettlebells, realize it's just for fun and probably counter productive.

女房いわく、ケトルベルは単なる娯楽　ストレンクストレーニングとしては有害かも
